It's not a personal priority, but it would be nice to add the remaining stemmers from snowball--perhaps by writing a snowball to python translator.

I might do this myself, either post-diss or if I need a break from writing, etc.

May it be better to remove snowball stemmers altogether in favor of pystemmer? https://github.com/snowballstem/pystemmer
