AFAIK, non-patched 'result_of' requires a FunctionObject template
to have a "base class" or "user-defined constructor".
VC++ dislikes something like Aggregates? I'm not sure.

Well, if a FunctionObject template doesn't have a base,
I recommand to write an empty default-constructor; until patched version 
comes.
(Note iterator adaptors need DefaultConstructible FunctionObject.)
