        <pre>OK, a couple of points:

(1) You're referring to libc++'s <experimental/optional> implementation, not
<optional> which correctly implements all three overloads. You need to specify
this next time. Alternatively supplying a minimal reproducer will speak for
itself.

(2) You reference the C++ standard (n4618), however the C++ standard doesn't
specify <experimental/foo> headers. The library fundamentals TS does. 

(3) Libc++'s <experimental/optional> only implements LFTS v1, but the overloads
in question only appear in LFTS v2. Perhaps someday somebody will upgrade the
<experimental/optional> implementation but it's not priority since we have
already shipped <optional>. (Patches welcome!)

Closing this bug as a duplicate of the bug tracking optional's LFTS v2 status.
