This is definitely a bug somewhere.

Specifically, it is a bug in GCC, because the standard says in
"A name used in the definition of a member function of class X following
the function's declarator-id [....] shall be declared in one of the
following ways:
- shall be a member of class X or be a member of a base class of X
The trailing return type in a member function definition is part of the
definition and is after the declarator-id, so the paragraph applies.
Furthermore, the lookup rules don't make a distinction between different
kinds of members.
