Subject: [Boost-users] metaprogramming -- does a specialization exist?

Is there some way to check at compile time whether a particular
specialization exists?
E.g. I have a template class with two template arguments which are
commutative -- means they can be exchanged and the result is the same. Can I
check whether
type<A, B> exists and if not select type<B, A>?
