As someone who has worked in an almost exclusively-Python company for
close to a year, I have to agree that unit (and more importantly
functional) tests vastly speed up development, for exactly the reasons
outlined above. Perhaps Python needs them more than many languages
because of its lack of strong types, but I'm so enamoured with them that
I'm going to try to use them with everything I do.

We also use various other Extreme Programming-related things, such as
pair programming and code reviews, but nothing is quite so company-wide
and (to my mind) useful as the test suites.
