SublimeText has SublimeLinter and PycodeStyle installed, but I'm still 
familiarising myself with ST. Nothing is reported.

Any advice/correction/improvement would be most welcome...

Exactly!
(PyTest and coverage tools were no help - they import correctly (and 
test adequately), but I didn't open those (separate) modules to notice 
the multiple import-s)

Hope springs eternal ... there must be a better way???

(well yes, not wishing to 'flog a dead horse' (nor any horse for that 
matter) I'm pleased at the (lack of negative) response to my allied 
question about nested classes, which would solve the original problem)
