Then when gdb uses C++23, we can perhaps just s/gdb/std/ and not reformat everything. https://en.cppreference.com/w/cpp/ranges/enumerate_view.html ... in particular note (2) I guess we could go the other way but I tend to think it's better in the end to just use the standard names and not supply renamings of things.

It also uses a reference but I am not sure if that matters for us. Tom
