But isn't the class_type pointer hidden? AFAIK, you can't call a member 
function pointer as if it's function pointer with an explicit 'this' 
parameter. So how is the arg1_type classtype?
But on the other hand, that's what bind does - so you can bind the class 
instance to be called..
Really what's better is a mem_fun adaptor - like boost::mem_fun except at 
compile time, since the member function pointer is a template parameter.
* template <class PropertyKey, class Functor> function
-> function<print_function, ct_mem_fun<void,A,&A::print> >

That way you could also call nested functors inside the class, which allows 
more flexibility.

So disregard that code for extending function_traits to work with member 
function pointers =P It wasn't very good anyway.
