Agentic programming workflows rather remind me of genetic programming. The agent has a validation step that looks like a fitness function, and both run iterative trials.

Playing with optional type signatures in Python, I realise that the return type is the most important to me. I'd much rather have a function with only a return type instead of a function with only parameter types. It's often quick to add too.

I'm working on arity errors in Garden, my toy programming language. Rather than just saying "expected 3, got 4 arguments", I'm trying to report where the extra argument is, or what extra argument was expected.
