[cfe-commits] [patch] decltype in mem-initializers

[Richard Smith]

LGTM.

It wasn't instantly obvious to me why we can be sure that the kw_decltype
token has been annotated here; I imagine a comment indicating that
ParseOptionalCXXScopeSpecifier will convert the next token into such an
annotation would be useful for future readers.
