New description:
#8810: Implementation of Stanley symmetric functions for types A,B and
A/B/C/D affine
Depends on #8811.
Based on the combinatorics of Pieri factors
(sage/combinat/root_systems/pieri_factors.py)
Currently, there are two implementations of the maximal Pieri factors:
a combinatorial implementation and a type-free implementation using
translations in the affine Weyl group. Type D affine Stanley symmetric
functions are still conjectural, but type D affine Pieri factors have been
established rigorously.

Comment:
Depends on #8811, which needs review.
