I think the trouble with ideas like that is once you accept that @a ,= 'd'; Is necessarily a short-form of: @a = @a, 'd'; You can see the thing you need to decontainerize is that @a on the RHS: @a = | @a, 'd'; But you can't get at it in the short form. (So you wouldn't normally try to use the short form with arrays.)
