This is so cool!
./tdd.sh tests.py application.py
Define the tests first, then run the bash script and it will iterate on application.py until the tests all pass
Here's a Bash script that stitches together `llm` and `files-to-prompt` (from @simonw) to run an iterative TDD loop to make a set of tests pass.

This effectively automates the green part from the standard red-green-refactor loop.

If this poorly-designed feature is really added to Python, we lose a principle I’ve always taught students: “if you see an undocumented constant, you can always name it without changing the code’s meaning.”
The Substitution Principle, learned in algebra? It’ll no longer apply.
Important to note, however, that the semantics of this can be quite different from switch. The cases don't simply check equality, they rebind variables that match the specified pattern. For example:
ALT NOT_FOUND = 404 retcode = 200 match retcode: case NOT_FOUND: print('not found') print(f"Current value of {NOT_FOUND=}") # not found # Current value of NOT_FOUND=200
Great work everyone! Can't wait to use it.
