Hi Steven,
I disagree with you there. A large problem, along with poor
documentation, is no testing.
If doctest makes it much easier to test, use doctest. If you prefer
other methods then use them, but applaud Bearophile for not only
testing, but showing his tests. If it doesn't interest you then skip
it, but it at least has shown that Bearophile thought to test his
code.

The blatent and interesting bugs are usually the first thought of, and
found. It usually takes thorough analysis of the program under testing
before it is wise to remove a test and trivial, or uninteresting are
not usually reasons to remove a test wothout qualification.

Bearophile might want to use another file for his doctests, but that
would hardly help when posting to usenet.
