I'm not at all sure modifiers will be stackable, as this grammar implies.

I am hoping that Larry will also give us:
[ LABEL: ] for[each] (scalar, scalar ...) ( list ) { block }

Currently:
21. sub identifier [ ( prototype ) ] [ is properties ] { block }
22. sub [ ( prototype ) ] [ is properties] { block } [is properties]
Though I would *much* prefer to see:
21. sub identifier [ ( prototype ) ] [ :traits ] { block }
22. sub [ ( prototype ) ] [ :traits] { block } [is properties]

May also have a redundant comma after the last element.

Need to recast this in terms of statement separators and null statements.

"its effect on scoping"
(we probably don't care about its pyschological demeanor ;-)
