Shouldn't this be WTF_MAKE_FAST_ALLOCATED_WILL_BE_REMOVED? I'm curious why this
CL compiles without adding _WILL_BE_REMOVED.

Thanks! Nothing at compile-time disallows defining new/delete for a GC'ed class.
I'll look into checking against redeclaration in the plugin. (I actually thought
that was added already, but that was on the branch plugin).

 public:
     static void provideTo(Document&);
