Is it safe to use std::bind to pass a member function to boost::signals2::signal::connect()? In other words, is boost::bind and std::bind interchangeable?
It compiles with VC++ 2010 SP1, but the template code is way over my head and I'm afraid I might be venturing into undefined behaviour territory.

std::bind is a Standard Function Objects that acts as a Functional Adaptor i.e. it takes a function as input and returns a new function Object as an output with with one or more of the arguments of passed function bound or rearranged.
The return type of std::bind holds a member object of type std::decay<F>::type constructed from std::forward<F>(f), and one object per each of args... , of type std::decay<Arg_i>::type, similarly constructed from std::forward<Arg_i>(arg_i).
I'm not experienced in the subject by I would expect connect to take anything that implements a valid function call operator. It should be safe to call it with any function or function object that matches the signature, be it boost::bind, std::bind or anything else. Boost libraries are designed to be generic, so they usually don't go picking each others implementation details.
