Re: [boost] [Proposal] A little reasonable modification of boost::bind_t

Hi, everyone,

I'd like to propose a little modification of boost:: bind to expose more information in boost:: _bi:: bind_t.

Here is my motivation problem. Suppose this is a function which takes boost: :_bi::bind_t as a parameter. But at the same time, I'd like to enumerate all binded parameters and do something for specific types, like the following pseudo code shows.

template< class F> void foo(F & f) { foreach(T& arg, f.arguments()) { if(boost::is_same::value) //here ID_t is a user specific type //do something for arg. } }

A polymorphic function object does not have a single type for the arguments nor even a single arity.
