Dmitry Petrov 2cd6c85cc7 Syntax forms 'a<T>::foo', 'a?::foo' have special cases resolved for future releases.
'a<T>::foo' is reserved if 'a' is a simple name and can be resolved as an expression
(this can be extended to 'a.b.c<T>::foo' case, although that is rather hard to implement using PSI).

 'a?::foo' is reserved if 'a' can be resolved as an expression.
