S. Davis Herring <herring at lanl dot gov> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |herring at lanl dot gov --- Comment #14 from S. Davis Herring <herring at lanl dot gov> --- (In reply to Jonathan Wakely from comment #0) > I think the qualified name detail::f should find ::detail::v7::f In case it helps, this is now unambiguously the case ([decl.meaning]/2.2 in the current draft describes the lookup, but here it's just ordinary qualified lookup).
