At one point not so long ago, we had a very enlivening discussion on-
list about splitting off chunks of modules into their own
subdistributions. Everyone seemed relatively on board for the idea,
which is somewhat summarized here (bioperl-dev is also mentioned):
The key aspect that started this all is to have a lean (read: few
dependencies, relatively stable) core set of modules. Other related
modules which add additional dependencies could be moved into a
bioperl-tools. And (finally) anything lacking the guarantee of API
stability would be bioperl-dev. I think several other alternatives
came up but these seemed to be the final ones.
core = minimal functionality
tools = complete functionality (requires core)
dev = experimental APIs, etc (requires core and possibly tools)
If we claim that bioperl-live is representing 'core', we are going the
direction of code bloat by dropping all new (possibly untested) code
there. However, if we can somehow package up the 'live' modules into
distinct bundles as delineated above that also solves the issue, so
any new code can go in. Depending on which avenue we take, I either
agree or disagree with Sendu on dropping all new code into bioperl-
live (like a coding version of Schrödinger's cat).
Anyway, I saw a distinct lack of progress towards any solution, so I
just took the initiative to set up *SOMETHING* so progress is made,
one way or the other. If bioperl-dev ends up being a temporary spot in
the road I don't have a problem with that, just as long as we come to
some consensus on what to do, how to approach it, and make progress
towards that goal.

I'm a big fan of branches (I ran all the feature/annotation refactors
off a branch). So I have no problem with anyone wanting to test stuff
out there, with the idea that stuff be merged back in at some point.
(Aside: do we really need to retain feature branches? Most projects
remove them after they are merged back in)
Anyway, I don't have a problem with new code being added in and adding
new devs. And there isn't anything that prevents any dev from
committing to any of the other bioperl-* repos AFAIK. But a consensus
would be nice, and the sooner the better.
