Make sure to put the rice in a freezer if you're going to store it for a long time. This is important to prevent bugs, especially in hot and damp weather. If that's not possible, sprinkle some dried chilis or peppers.
I've heard a podcast interview of a very talented person. He said that he left MS because of "internal politics". I thought it was personality conflicts or something, but stack ranking might explain a lot.
Thank you for raising the question. I think it's an important one to think about. I constantly hear about good things about the REPL experience of LISP family languages. You can set up a code fragment (the test in your example) to run constantly in the background as you edit. Then you can jump to the REPL anytime and interact with the state.
I myself am more on the ML-family side of FP, where you'd encode the expected behavior with an expressive type system and work with the type checker (the smart compiler) to implement that behavior.
One important thing to note is that the type checking process is also a fast feedback loop. The difference is that it's often on the abstract level and you're more concerned about the expected behavior instead of the actual behavior.
It's harder to write, but the advantage is that you'll have more confidence once it type checks.
Of course, the two styles are not mutual exclusive, just that the tooling ecosystem will often reflect the culture of that language family. And it's easier to add a simple watch make task, but harder to go the other way around.
