Again, good catch.

We have that in there because for some of our tests, we overload the subscript operator to take no arguments, which is a C++23 feature. See my comment here: https://github.com/llvm/llvm-project/pull/95220#discussion_r1955916314 as @carlosgalvezp had noticed this too.

Correct me if I'm wrong, but to my knowledge we cannot specified the C++23 dependency for the tests individually, but would have to have a new file with new run commands. Or is there a more elegant way?
