Excellent summary of why an explicit index is a Good Thing as compared
to the programmer doing it himself.  I think the syntax would need to
be different though, how do you use implicit $_ and an index?  (Don't
Do That is not an answer because people will want it)  Here are some
ideas:

        # Gosh, let's overuse : like python! ;-)
        for $item:$index (@array) { ... }
        for :$index (@array) { ... }            # $_ and counter

        for (@array : index($index)) { ... }
        
        for (@array) $index { ... }
