Well, I knew all that, except I didn't think you could do it in the context
of a complex statement suite (i.e., after a colon). I attributed its working
to exec because I thought it wasn't otherwise allowed after a colon. Bad assumption.

Well, good to get that straight (though maybe not for readability, if I'm tempted
to pack too much on a line ;-)
