Wing doesn't read the .pi files when there's already a .py file present,
so that probably won't help. Using isinstance would work if you can
import what you would essentially have put into the .pi file. It may
not be the greatest solution since you'ld have an isinstance under
each enum() call.
One idea would be to change from runtime creation of the classes to a
preprocessor of some type, so that your code imports the output of
that processing rather than the above source.
Note BTW that the auto-completion in the Debug Probe and Python Shell
would correctly handle this case since they source their data from
the live runtime.
