The "primaryjoin" model has been stretched a bit further to allow a join condition that is strictly from a single column to itself, translated through some kind of SQL function or expression. This is kind of experimental, but the first proof of concept is a "materialized path" join condition where a path string is compared to itself using "like". The :meth:.Operators.like operator has also been added to the list of valid operators to use in a primaryjoin condition. fixes #3029
I'm interested to see how this turns out.
