Hi path algebra fans!
I am having doctests failures in #8678 because of the following
"feature" of quiver path algebras:
sage: P = DiGraph({1:{2:['a']}, 2:{3:['b']}}).path_semigroup()
sage: A = P.algebra(GF(7))
sage: A.list()
[Free module spanned by [e_1, e_2, e_3] over Finite Field of size 7,
Free module spanned by [a, b] over Finite Field of size 7,
Free module spanned by [a*b] over Finite Field of size 7]
And indeed ``A.__iter__`` states that it iterates over the homogeneous
components of A. This sounds bad, since the general convention for
parents is to have __iter__, list, ... iterate over its elements. And
indeed some code that makes this assumption explodes.
Can we just rename this feature? Is it actually useful?
Cheers,
Nicolas
