Sorry for looking in every hole.
Just a  suggestion.

A= condition and first or second
problem is in case when first in (None,0,[],"").
May be invent new operator 'take'.
take - returns right operator when left evals to True and stops 
computing condidtional expression.
Then we could write:

A = condition take first or second.
A = x==y take w or s
A = z is not None and q!=12 take [] or allowable(z,q) take [(z,q)] or 
"Impossible"

Ok, it might looks ugly. But may be not.
