<pre>FWIW, C++ is exploring explicitly rejecting these constructs
(<a href="http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2021/p2362r2.pdf">http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2021/p2362r2.pdf</a>) and I
expect WG14 to receive a similar proposal.
I think it's reasonable for our implementation-defined behavior here to be to
reject those constructs. In fact, we recently strengthened our handling of this
in <a href="https://reviews.llvm.org/D106215">https://reviews.llvm.org/D106215</a> to also apply to L'ab' in addition to u'ab'
and U'ab'.
Closing this as WONTFIX, but if you know of a reason we *should* be allowing
these constructs, please reopen with information about your use case.</pre>
