One might replace type signatures with comments, of course, and so convey better information, but that is more work, hence we poor ignorants will settle for signatures.

You mean one might add comments _as well as_ type signatures, of course. The only thing worse than no comment is an incorrect comment. At least type signatures are verified by the compiler, and cannot lie.

Nah, useless comments are also worse than no comments, as they make people think there are useful comments, which prevents useful ones from being written. Better than wrong comments, as it's easier to tell that you should ignore them. -- Aaron Denney -><-
