[Boost-users] [type_traits] Checking for same class template

The type_trait is_same can be used to check if two types are the same. Is there a type_trait to check if two templates are the same ? A template class I am developing takes as a template parameter a template rather than a class and I would like to check, to be used in MPL, whether the template being passed as a template parameter is the same as another template.
