most people I know eschew the use of with-redefs for testing because it's hard to verify that the testing environment is configured correctly as the codebase changes (but otherwise I second the points about immutability by default, and static/pure functions!)
Agreed - concretely with-redefs forces single threaded test execution. So eg you can’t use the eftest multithreaded mode.
Explicit dynamic bindings are better if you need something like this since those are thread local.
