The value of the FTM is made-up.\n\nThe converting constructors from `optional` are tedious to type.\nMaybe deduce the argument and centralize the implementation?\n\nNoted a few things to address in P2988R12, editorially / easy LWG issues.\n\nmake_optional: the proposed change breaks\n` make_optional({braced-init-list})` wanted? Disabled for now.\n\nlibstdc++-v3/ChangeLog:\n\n\t* include/bits/version.def (__cpp_lib_optional): Bump the\n\tfeature-testing macro.\n\t* include/bits/version.h: Regenerate.\n\t* include/std/optional (optional): Add specialization for\n\treferences. Do minor amendments to the primary template as\n\tper P2988R12.\n\t* testsuite/20_util/optional/requirements.cc: Amend the\n\tfeature-testing macro test.\n\t* testsuite/20_util/optional/requirements_neg.cc: Amend the\n\ttesting of optional.\n\t* testsuite/20_util/optional/version.cc: Amend the\n\tfeature-testing macro test.\n\nThanks for taking the time to contribute to GCC!\n\nPlease be advised that https://forge.sourceware.org/ is currently a trial\nthat is being used by the GCC community to experiment with a new workflow\nbased on pull requests.\n\nPull requests sent here may be forgotten or ignored.
