--- Comment #1 from Darin Adler <darin at apple.com> ---
I guess we can do this.

We do this for Ref by asserting the pointer is not null in Ref::leakRef. We don’t do this for RefPtr.

Longer term I think we want to move from ExceptionOr to std::expected. Is that right? If so, we should figure out if std::expected can assert for cases like this.
