And I can’t imagine why you want to be able to identify multiple different files by similar names where only casing differs. This is a completely arbitrary opinion and nothing fundamental. > a.txt != A.txt != a.TXT and so on. They're different names of different files. Only if you define your != operator that way. It’s completely reasonable to have equality under some normalization.
