It could also allow std::expected to be even easier to use!

const auto myExpected = Meow();
assert(myExpected.has_value());
const auto myValue = std::move_as<ValueType>(myExpected);

But I believe that could be a long-shot, I would use it myself, not sure
whether other programmers would find it.. intuitive, your call.
