Constraints wouldn't help when the template name is overloaded
and passes the constraint checks of several different template
implementations; specializations narrow things down for
overload resolution.
Unless I'm misunderstanding the OP or everyone else in the
thread somehow :/
That's exactly right, you've probably put it better than I have!
Specializations are quite different from constraints and I have
found as you said that specializations are a great way to narrow
things down for overload resolution. I use them to dispatch
methods and they are the easiest way to specify a known set of
kinds on a method set. When you narrow to your specialization set
like that it will always work in the same way - no rouge types
will mess things up.
