Research direction
Read issue #1244 for context, then inspect the PostOrder entry points for foldl and foldr' and how their default implementations behave. Done means confirming whether both folds are productive for PostOrder and implementing them manually if the defaults are insufficient.
Written by the indexing model from the issue text.
Description
In the course of #1244 I realized that foldl and foldr' can be productive for PostOrder. I'll take a look at how well the default implementations work, and implement it manually if needed.
