package is something that is not really happening right now though. In
cases like scikits.image/learn/statsmodels, which are active, growing
projects, that of course doesn't make sense, but for packages that are
stable and see little active development it should happen more imho.
Example 1: numerical differentiation. Algopy and numdifftools are two
mature packages that are general enough that it would make sense to
integrate them. Especially algopy has quite good docs. Not much active
development, and the respective authors would be in favor, see
Example 2: pywavelets. Nice complete package with good docs, much better
than scipy.signal.wavelets. Very little development activity for the
package, and wavelets are of interest for a wide variety of applications.
Would have helped with the recent peak finding additions by Jacob Silterra
for example. (Not sure how the author of pywavelets would feel about this,
it's just an example).
I'm sure it's not difficult to find more examples. Scipy is getting
released more frequently now than before, and I hope we can keep it that
way. Perhaps there are simple reasons that integrating code doesn't happen,
like lack of time of the main developer. But on the other hand, maybe we as
scipy developers aren't as welcoming as we should be, or should just go and
ask developers how they would feel about incorporating their mature code?
