Hi everybody,

in addition to my previous question, first of all this :

template<typename F>
void foo(const F& f)
{
std::cout << boost::function_traits<F>::arity << std::endl;

}

foo(f);

was a great solution for a free functions, so thanks to everybody for
answers but, alas, this is not a solution for both member functions
and function objects : boost::function_traits cannot work with any of
these types. any ideas ?..

best regards, Paul Sujkov

Thanks for anyone trying to workaround this (if there were any)
issue is solved, no answers are needed anymore...

best regards, Paul Sujkov
