Bug ID: 100084
Summary: using enum lookup isn't type-only
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: barry.revzin at gmail dot com
Target Milestone: ---
>From Stack Avarflaw (https://stackoverflow.com/q/67096550/2069064):
namespace A { enum A {}; };
using namespace A;
using enum A;
gcc trunk rejects this lookup as ambiguous, between the namespace A and the
enum A. But our lookup in this context should be type-only, so the namespace A
should not a candidate.
