Emile,
Actually, I have already broken it out into 4 or 5 separate lines. The
one-liner is cool for "Hey, look what I can do", but isn't for code
maintenance. What I was striving for a happy medium between compactness and
readability.

I couldn't find a way to reverse the order of the elements to ultimately for
a dictionary, so I resorted to this hack instead.
