It doesnt seem necessary yes, im wondering what purpose the performance tests serve? Far as i can tell they seem defunct.

Additionally, the tests will require extensive changes as many tests still have mismatched signatures, one such example being https://github.com/vgvassilev/clad/blob/5cb3c18e0c5cb4b41d0dcc80076eb97b61c61fae/test/Hessian/Hessians.C#L146C1-L162C3

I would merge the two code blocks for the class method and regular function into one, but for some reason i cant seem to get Sema::LookupName to look inside classes...
