Dear Language Designers: Please Copy `Where` from Haskell

The only bit I dislike about Haskell's `where` is that it's only in scope for one case of a named function, e.g. in the article only the bottom quicksort had lesser and greater in scope.

As you appear to be the author, line 3 of the first code example has a “qsort” where a “quickSort” should be.
