That isn't *quite* what I need.  I'm aiming to detect the presence of 
operator[] (or any other member function, for that matter) independent 
of its precise signature (and it looks like the macros that 
has_member_function.hpp defines need a signature).  Do you have anything 
that will help in that regard?

Thanks for the reference though, this might come in handy ;)
