Thanks! The stuff that ASTs let you do really flexibly is almost always lost to people because they're not aware of it. A lot of other developers would try to do this with string or regex matching, and that often leads to painful experiences.

Agreed. Simple checks like these are trivial: A call to function "Foo" Must always have an argument matching the regexp "/blah/". Otherwise raise an error. And they're so lightweight you can add them to any CI/CD/automation steps in your repository. Once you get a few things like that, or validating naming-standards, you can roll them up into a simple "linter".
