perhaps another way to do this if you want to avoid repeating the return
expression would be a small lambda that contains the return expression and uses
a simple name - so the returns can just be `return ret();` ? (or I guess nest
the switch in an `if`, or in another function that uses ref parameters to
populate the result)
Though in this case it's only twice, so I'd probably repeat the expression?

I second the question - though I'd push back on the "This is a message users
will see" - unreachables won't be seen by users, they get lowered to UB in
release builds - the text isn't in the program anymore. The text is only for
Clang developers (and/or clang-as-library users).
