--- Comment #27 from Darin Adler <darin at apple.com> ---
Exactly. This use of std::exchange is something Chris and I agree on! We are still debating whether to ever move from WTF::Optional to std::optional; a related but distinct topic.

For what it’s worth, my patch to use std::optional did not show any failures in EWS regression tests, but that doesn’t prove whether or not it introduces bugs that were not detected by those tests.
