Describe the bug I can't use any of the name_of/display_name_of/etc. functions in compiler explorer.

To Reproduce Steps to reproduce the behavior:

  1. Go to the following example: https://godbolt.org/z/zK734b9Mo
  2. Observe that it doesn't compile

Expected behavior It should compile and should print out the names.

Screenshots If applicable, add screenshots to help explain your problem.

Environment (please complete the following information):

Additional context I've also tried prefixing them with std::meta, with the same results.

You need to use display_string_of instead of name_of. Some names of the meta functions changed. I recommend checking https://github.com/bloomberg/clang-p2996/blob/p2996/libcxx/include/experimental/meta for exact function signatures.
