No, I don't think so. We would end up having to deal with the
combinatorics of various ways to combine generators.

As I've said in my other email, we may well move to a loader which uses
the version info from the path rather than the library name. So for now
just put in what's compatible with the released version of AGILe and
we'll sort out the long-term issues with Genser.
