One might replace type signatures with comments, of course
You mean one might add comments _as well as_ type signatures, of course. The only thing worse than no comment is an incorrect comment.
Personally, I'd be inclined to extend that list to include vague comment, trivial comments, ambigous comments. And if you ever need to comment on *how* a function works, the function is too complex and should be refactored. Spend your time making the code readable instead. (Readable code is more important than correct code -- readable code with bugs can be made correct, with unreadable code you can never be sure of its correctness.) </rant> :-) -kzm -- If I haven't seen further, it is by standing in the footprints of giants
