Oops, thanks Jakub, I didn't realize we don't run the testsuite with
-std=c++23 yet.
I guess it'd be too expensive to add another std to the testing matrix
at this point, but I wonder if the test harness should at least run the
testcases inside cpp23/ with -std=c++23? Something like the following
seems to work.
(And since -std=c++11 also isn't part of the default testing matrix
anymore, perhaps we could give the testscases inside cpp0x/ a similar
treatment too?)
