boost::function provides these as arity, arg1_type, arg2_type, etc.

There is no way to determine the arity or arguments of a bind expression,
because the answer is not unique.  The function objects created by 
boost::bind
a) ignore extra arguments
b) may be able to handle different types of arguments depending on
   the bound function object(s).
