Comment:
Corrections made. I guess I was just being overly cautious with the copy.
It seems to work fine without (i.e., self remains unchanged).
I greatly increased the spectrum of failure testing as well.
Also, I was overly ambitious in my coercing in __call__ so I scaled that
back slightly. I was able to produce a weird behavior with the example in
algebraic_scheme.py line 2472. That example now raises an error.
As for generic/morphism.py. I couldn't find anything locally that was
causing the deletion. Looking at each commit individually (locally and on
trac), nowhere was it removed. Now that I've pushed these new commits up
the issue seems to have gone away. I guess trac was just confused...
