I don't care whether it's "interesting", I just want to get some work
done. And since most of the text processing tools in Unixes that I
would otherwise use (grep, sed, tr) don't support Unicode, and are
inconsistent in their regular expression notation to boot, it would be
nice if I could write regex operations in a single, consistent
programming language. Python is a single, consistent programming
language, but as you say, it doesn't lend itself to one-liners.

Hmm, I may give that a try...thanks!

Well, I guess I could translate some other char (one that's easier to
count than spaces) into indents, too.
