Bug ID: 57270 Summary: std::is_function ignores function ref-qualifiers Product: gcc Version: unknown Status: UNCONFIRMED Severity: normal Priority: P3 Component: libstdc++ Assignee: unassigned at gcc dot gnu.org Reporter: lucdanton at free dot fr Following the resolution of 57253 (http://gcc.gnu.org/bugzilla/show_bug.cgi?id=57253) it seems worthwhile to point out that there are missing specializations of std::function such that e.g. static_assert( std::is_function<void()&>(), "" ); is triggered.
