  icomment: Interestingly, while Tcl 8.6 was changed to disallow non-optional
            arguments following optional arguments, it didn't address non-unique
            names in the same wash.

            Btw., your expectation ("it'll just discard the first two args at run
            time") is not the right one, because instead it only uses the first
            one of the values.
