The reasoning behind this patch is a discussion I was having with someone who works on code which does use @synchronized extensively, and they complained about Clang not supporting implicit conversions when using C++ wrapper objects. I don't have a strong reason to request this patch be merged, but it would be nice to be able to say that issue is fixed.
