I think I wrote that before I found out about list comprehensions.  How
new are list comprehensions?

I do like that, it's clearer.

Okay.

Hmm.  There's an interesting question -- does this work as-is?  I'm
assuming it must or it would have blown up on me pretty badly, so
presumably those backslashes are getting passed through untouched
already.  But if that's just coincidence (they happen not to be valid
\-sequences), I should definitely fix that.
