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!
