Agreed, but it seems like every suggestion other than “foo(:)” which doesn’t use such a character ends up potentially conflicting with some other aspect of functions. That example Rintaro Ishizaki posted about the potential confusion regarding “_” in switch statements doesn’t compile now, but I’m not sure if there isn’t some useful advanced pattern-matching stuff that might need that syntax. And we don’t like “foo(:)” because it breaks the “colon -> argument” rule that exists in the rest of the language.
