Hmm, that will work only if neither bind nor its dependencies include "if.hpp". 
They don't right now, but I wouldn't rely on it. I think I'd prefer just to
fix the names in the header to match the ones used by the bind specialization 
-- those are considerably less likely to change. 

OK, fixed. Thanks for the report!
