Hi Dana...
I'm also wondering... can't we use python itself to do that?
My main problem, the way it is, is that it doesn't work with most of my code
because of importing errors (I have a part of it done in c++, so, jython
would never be able to get that)... getting the pythonpath might be a
problem too (but not as difficult to solve).
I know it is just a first working version (and I don't wanna be a pain in
the ass), but based in jython, I think that I would never be able to use
it... (unless of course, I don't use any c++ modules and that we are able to
get most of the python modules working into jython - and I think that all
that don't work in jython right now are in c++ - or depend on features
available on newer versions of python, as jython currently supports version
2.1 - I think - ).
So, basically, what I want to say is that it is good the way it is for
Jython development, but when it comes to develop in python, I think that
jython just hasn't arrived there yet... (still version 2.1) and for some
things like dependency on c++ modules, it probably never will (and this has
never been its purpose).
Of course, we could let the user choose what to use, if we want to extend
the plug-in to develop in jython, but I think that it must support python
without dependency on jython.

Fabio,
yeah, there are some rough edges.
I checked PyAlaMode with the same code.
See comments inline:

PyAlaMode didn't know what to do with 'self.' here either and didn't
offer any autocompletion suggestions, so I think ours is at least at
that level

Yeah, looks like what I will have to do with classes based on other
classes is to introspect the superclass(es).
I may have something fixed and in the hopper in a day or so.
I may have to "steal" better Python introspection code (from PyAlaMode
maybe). Mine obviously does not recurse into antecedent classes.
Thanks Fabio!
