boost::function doesn't support dumping arguments, unless I'm
mistaken.
Do this:
template <class T> struct incomplete;
template <class T>
int q(T)
{
incomplete<T> a;
}
int x = q(boost::bind<int>(f,_1,_2));
The error message will tell you that incomplete<some_nasty_type> is
incomplete.
Write down that type and use it to declare the result of calling
boost::bind.
