13.2 [temp.param] paragraph 13 says:
The scope of a template-parameter extends from its point of declaration until the end of its template. In particular, a template-parameter can be used in the declaration of subsequent template-parameters and their default arguments.Is the following well-formed?
template<class U = U> class X { ... };
