What about

template<class Wrapped<typename T...>, typename ArgList... >
class bind;

bind<vector, foo(bar(_1)), _2>

That should work, even if 'Wrapped' requires it template arguments to
conform to some exotic concept.
Or may be something like this:

bind<vector>(foo(bar(_1)), _2)

Untested of course, and I'm not sure how concepts interact with
template template parameters.
