What if it's a more complicated example? len(sorted(a_list_of_strings.casefold())[:100]) where the len() is supposed to give back a list of the lengths of the first hundred strings, sorted case insensitively? (Okay so it's a horrible contrived example. Bear with me.) With current syntax, this would need multiple map calls or comprehensions: [len(s) for s in sorted(s.casefold() for s in a_list_of_strings)[:100]] (Better examples welcomed.)
