Re: [boost] [type_traits][cw] is_convertible compile failure

I'm far from being an expert in this area, but, what happens if you change the second ctor of any_conversion (which is only to kick in for function references) from

template <typename T> any_conversion(T&);

to

template <typename T> any_conversion(T);

I don't believe that would help: in fact it would make the two constructors ambiguous, and in any case you can't pass a function type through a by-value constructor. John.
