Doctests in modules aren't tested; are failing

There are two doctests, one in pytools and one in pytools.decorator. These don't seem to work and aren't regularly tested.

decorator should really be removed and replaced with https://pypi.org/project/decorator/. So I don't feel responsible.

The other two aren't really worth the effort. I've deprecated them in !17 (e4c20b95).

(But thanks in general for requests of this type, even if this one ended up a bit anticlimactic.)

As in, it's the same code already anyway.
