I DO want it to be possible with future fixed-sized arrays. This is not a user-side question, but implementor-side. I’m asking if the parsing routines for it would conflict with the current array- and dictionary-literal rules, since they will co-exist. If this syntax would make determining whether we have an enhanced array literal or a dictionary literal too hard, then we should change it before anything is finalized.
