--- Comment #5 from Adam Ryan <gcc.gnu.org at ajryansolutions dot co.uk> --- Hi Andrew, is that the test case you want to go into the patch? I had thought since that the test case would be better with parameter pack containing function references as the current one only compiles from c++20. I was going to suggest it for a V2 patch but I haven't seen any interest in the submission so far.
