[Bioc-devel] Stability of biobase eSets

Just a quick "developer" question--how stable are the data structures and
methods for dealing with eSets likely to be?  I have been using eSets much
more recently just for data handling, but I think I would probably like to
extend them some and don't want to do that (given the availability of older,
stable data structures) if they are going to be changing much.

Thanks,
Sean
