simpleloader = Loader1()
s1 = simpleloader.loadTestsFromModule(pkg) # Just top-level module
# as usual
discoloader = DiscoLoader(simpleloader) # The concrete loader is
# an arg. It is used to actually
# load tests out of single

I understand that loadTestsFromPackage is a candidate. I'm not sure
about its benefits, especially because AFAICS and IMHO there is no
need to include loadTestsFromPackage in order to allow discovery. I
think that the option I mentioned above is more dynamic and is
suitable for diverse discovery strategies, varying apart of the code
for the real | concrete loader.
Could we pls keep focused on the pros & cons of both approaches with
concrete arguments ?
