Technically, this means that lookups that find class members and those that don't will be mangled the same, despite the impact on ADL, but the mangled-as-written mantra already causes us to gloss over stuff like that, and I can't think of a situation where it's a problem with valid code.

I don't see a resolution to this. Do we stick with GCC's "(*this)."
mangling, or mangle as written?
