I suppose that's true. And obviously, one could create awhile from whilet. But from a language design perspective, shouldn't there be the entire set of anaphoric operations?
(I was going to complain how whilet doesn't make sense, and isn't at all like iflet or whenlet, but then I realized whilet isn't "while t", it's "while-let" with the overlapping "le" compressed into "whilet". Well, chalk one up for pg et al. Cool name.)
