Subject: [PATCH 02/20] Use explicit `this->` for dependent base members

Might have accidentally worked with implicit `this` back in the day, but
since base classes can be specialized, lookup can only happen after
instantiation, which prevents implicit `this` in referring to its
members with all conformant compilers.
