I feel a bit silly -- I don't quite like arguing about names and such.
Also I'm not particulary bound to any naming scheme, so let's discuss
something more interesting and useful instead.

I'm aware of that. My point is a bit different: I was explaining why I didn't
re-use the code from factor.cpp.

I was going to convert factor.cpp myself, but I didn't do that because 

- it might conflict with your changes, so this needs to be coordinated,
- if my patches will be rejected that would be a waste time.

I don't think upoly (and associated functions) will change. Anyway, I'll
update all call sites in a case of any incompatible change(s).

Best regards,
