[libcxx-commits] [PATCH] D94452: [libc++] Support immovable return types in std::function.

[Arthur O'Dwyer via Phabricator via libcxx-commits]

Quuxplusone updated this revision to Diff 318264.
Quuxplusone added a comment.

Support `std::function<const NonCopyable()>`, and then discover that `std::function<const void()>` wasn't fully supported either. This is now fixed.
However, the unit test for the fix might be unacceptable, because it inevitably triggers `-Wignored-qualifiers` and I can't figure out how to shut it up. @ldionne, any ideas?
