I could not find `group-by` using the Browser. Grepping the source tree, it
turned up in `grouping.extras`.

`collect-by` is a useful thing, got to keep it in mind. I remember
implementing something very similar not too long ago.

That may be a good idea. I'm regularly rereading the documentation for
`sequences` and `sets`, so maybe a little pointer to adjacent vocabs (at least
*.extras) could be made.
