We are generating toDartValue(PassRefPtr<T>) to guarantee that toDartValue(T) is
declared before it.

[Anton Muhin, 2012/03/23 17:29:23]

Thanks a lot for bringing this.  I still hope that if we put this into
DartDOMWrapper.h, everything should work smooth.  Am I missing anything?

[podivilov, 2012/03/26 09:45:07]

DartArrayBuffer.h generated header looks like this:

#include "DartDOMWrapper.h"
...
Dart_Handle toDartValue(ArrayBuffer* value)
{
...
}

If toDartValue(PassRefPtr<T>) is defined in DartDOMWrapper.h, it would not
compile because ArrayBuffer is defined in namespace WTF.

+// and do not generate it.
+template<typename T>
+Dart_Handle toDartValue(RefPtr<T> value)

-    // FIXME: create list from vector for primitive types
-    // without element-by-element copying and conversion.
