Tangentially, I noticed that we have a "starts_with" function but no corresponding "end_with". It's been a while but there used to be a systemic inertia working against adding minor useful functions such as these. With the new documentation layout I would at least consider updating the description for the normal functions with an example on how to formulate an expression that works contra-normally, and in the case where there does exist such a specialized function, naming it.
