+/**
+ * An object reference managed by the Dart VM garbage collector.
+ *
+ * Because the garbage collector may move objects, it is unsafe to
+ * refer to objects directly. Instead, we refer to objects through
+ * handles, which are known to the garbage collector and updated
+ * automatically when the object is moved. Handles should be passed
+ * by value (except in cases like out-parameters) and should never be
+ * allocated on the heap.
+ *
+ * Most functions in the Dart Embedding API return a handle. When a
+ * function completes normally, this will be a valid handle to an
+ * object in the Dart VM heap. This handle may represent the result of
+ * the operation or it may be a special valid handle used merely to
+ * indicate successful completion. Note that a valid handle may in
+ * some cases refer to the null object.
+ *
+ * --- Error handles ---
+ *
+ * When a function encounters a problem that prevents it from
+ * completing normally, it returns an error handle (See Dart_IsError).
+ * An error handle has an associated error message that gives more
+ * details about the problem (See Dart_GetError).
+ *
+ * There are four kinds of error handles that can be produced,
+ * depending on what goes wrong:
+ *
+ * - Api error handles are produced when an api function is misused.
+ *   This happens when a Dart embedding api function is called with
+ *   invalid arguments or in an invalid context.
+ *
+ * - Unhandled exception error handles are produced when, during the
+ *   execution of Dart code, an exception is thrown but not caught.
+ *   Prototypically this would occur during a call to Dart_Invoke, but
+ *   it can occur in any function which triggers the execution of Dart
+ *   code (for example, Dart_ToString).
+ *
+ *   An unhandled exception error provides access to an exception and
+ *   stacktrace via the functions Dart_ErrorGetException and
+ *   Dart_ErrorGetStackTrace.
+ *
+ * - Compilation error handles are produced when, during the execution
+ *   of Dart code, a compile-time error occurs.  As above, this can
+ *   occur in any function which triggers the execution of Dart code.
+ *
+ * - Fatal error handles are produced when the system wants to shut
+ *   down the current isolate.
+ *
+ * --- Propagating errors ---
+ *
+ * When an error handle is returned from the top level invocation of
+ * Dart code in a program, the embedder must handle the error as they
+ * see fit.  Often, the embedder will print the error message produced
+ * by Dart_Error and exit the program.
+ *
+ * When an error is returned while in the body of a native function,
+ * it can be propagated up the call stack by calling
+ * Dart_PropagateError, Dart_SetReturnValue, or Dart_ThrowException.
+ * Errors should be propagated unless there is a specific reason not
+ * to.  If an error is not propagated then it is ignored.  For
+ * example, if an unhandled exception error is ignored, that
+ * effectively "catches" the unhandled exception.  Fatal errors must
+ * always be propagated.
+ *
+ * When an error is propagated, any current scopes created by
+ * Dart_EnterScope will be exited.
+ *
+ * Using Dart_SetReturnValue to propagate an exception is somewhat
+ * more convenient than using Dart_PropagateError, and should be
+ * preferred for reasons discussed below.
+ *
+ * Dart_PropagateError and Dart_ThrowException do not return.  Instead
+ * they transfer control non-locally using a setjmp-like mechanism.
+ * This can be inconvenient if you have resources that you need to
+ * clean up before propagating the error.
+ *
+ * When relying on Dart_PropagateError, we often return error handles
+ * rather than propagating them from helper functions.  Consider the
+ * following contrived example:
+ *
+ * 1    Dart_Handle isLongStringHelper(Dart_Handle arg) {
+ * 2      intptr_t* length = 0;
+ * 3      result = Dart_StringLength(arg, &length);
+ * 4      if (Dart_IsError(result)) {
+ * 5        return result;
+ * 6      }
+ * 7      return Dart_NewBoolean(length > 100);
+ * 8    }
+ * 9
+ * 10   void NativeFunction_isLongString(Dart_NativeArguments args) {
+ * 11     Dart_EnterScope();
+ * 12     AllocateMyResource();
+ * 13     Dart_Handle arg = Dart_GetNativeArgument(args, 0);
+ * 14     Dart_Handle result = isLongStringHelper(arg);
+ * 15     if (Dart_IsError(result)) {
+ * 16       FreeMyResource();
+ * 17       Dart_PropagateError(result);
+ * 18       abort();  // will not reach here
+ * 19     }
+ * 20     Dart_SetReturnValue(result);
+ * 21     FreeMyResource();
+ * 22     Dart_ExitScope();
+ * 23   }
+ *
+ * In this example, we have a native function which calls a helper
+ * function to do its work.  On line 5, the helper function could call
+ * Dart_PropagateError, but that would not give the native function a
+ * chance to call FreeMyResource(), causing a leak.  Instead, the
+ * helper function returns the error handle to the caller, giving the
+ * caller a chance to clean up before propagating the error handle.
+ *
+ * When an error is propagated by calling Dart_SetReturnValue, the
+ * native function will be allowed to complete normally and then the
+ * exception will be propagated only once the native call
+ * returns. This can be convenient, as it allows the C code to clean
+ * up normally.
+ *
+ * The example can be written more simply using Dart_SetReturnValue to
+ * propagate the error.
+ *
+ * 1    Dart_Handle isLongStringHelper(Dart_Handle arg) {
+ * 2      intptr_t* length = 0;
+ * 3      result = Dart_StringLength(arg, &length);
+ * 4      if (Dart_IsError(result)) {
+ * 5        return result
+ * 6      }
+ * 7      return Dart_NewBoolean(length > 100);
+ * 8    }
+ * 9
+ * 10   void NativeFunction_isLongString(Dart_NativeArguments args) {
+ * 11     Dart_EnterScope();
+ * 12     AllocateMyResource();
+ * 13     Dart_Handle arg = Dart_GetNativeArgument(args, 0);
+ * 14     Dart_SetReturnValue(isLongStringHelper(arg));
+ * 15     FreeMyResource();
+ * 16     Dart_ExitScope();
+ * 17   }
+ *
+ * In this example, the call to Dart_SetReturnValue on line 14 will
+ * either return the normal return value or the error (potentially
+ * generated on line 3).  The call to FreeMyResource on line 15 will
+ * execute in either case.
+ *
+ * --- Local and persistent handles ---
+ *
+ * Local handles are allocated within the current scope (see
+ * Dart_EnterScope) and go away when the current scope exits. Unless
+ * otherwise indicated, callers should assume that all functions in
+ * the Dart embedding api return local handles.
+ *
+ * Persistent handles are allocated within the current isolate. They
+ * can be used to store objects across scopes. Persistent handles have
+ * the lifetime of the current isolate unless they are explicitly
+ * deallocated (see Dart_DeletePersistentHandle).
+ * The type Dart_Handle represents a handle (both local and persistent).
+ * The type Dart_PersistentHandle is a Dart_Handle and it is used to
+ * document that a persistent handle is expected as a parameter to a call
+ * or the return value from a call is a persistent handle.
+ *
+ * FinalizableHandles are persistent handles which are auto deleted when
+ * the object is garbage collected. It is never safe to use these handles
+ * unless you know the object is still reachable.
+ *
+ * WeakPersistentHandles are persistent handles which are automatically set
+ * to point Dart_Null when the object is garbage collected. They are not auto
+ * deleted, so it is safe to use them after the object has become unreachable.
