Hanging single quotation marks? You mean the ‘prime’ symbol? This comes up a lot in math to generate more variables that need a similar name—that’s why it ends up in Haskell and related languages. It’s not something weird. Granted the ASCII tick/apostrophe is neither the proper symbol for primes nor quotation marks (should be curly), but programmers are reluctant towards Unicode.
