Also, if the problem is man power, adding more code which makes the
whole package more difficult to handle does not sound like a future
proof path. Unless the goal of scipy is to become a bag of tricks
which may be useful to some people, without any commitment from our
Some parts of scipy are difficult to maintain because they have no
tests and no documentation - it is not even obvious what it is
supposed to do. I am afraid we can't have it both ways: if we want to
increase quality, given man power, we have to reduce the amount of
code which requires constant attention. If we want more features
first, then, we can continute like we do now. But then we can't expect
constant releases, which are relatively well tested.
