  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.
