I have it working in conjunction with Boost.Function. I extended 
boost::function_types::parameter_types<T> to also work for boost::function. 
Then, if the expression

is_callable< some_unknown_functor, boost_function_parameter_types >

evaluates to true, then I can do the assignment (the right one from a 
variant of functions),

boost::function< known_signature > = some_unknown_functor

this works fine (the parameter types come from the boost::function). What do 
you mean exactly by support for bind? As long as you supply the parameters, 
it should work. I.e., 

is_callable< unknown_bind_expression, known_parameters >

should also work. Could you provide an example / test case?

Thanks,
