Precisely, or even find a way not to require commas. I don't think we've seen a language that is explicitly designed to be as ergonomic / accommodating as possible to developers. Something that is the good protocol truism equivalent of "be liberal in accepted input and strict produced output". Granted that flies in the face of another programming language design best practice of having 1 way to do a particular thing.
