Yeah, this is a really great Haskell feature, and it often feels like magic the first time you see it. It's key to a whole lot of useful Haskell idioms. Well-known languages which do this include Haskell and Rust (where it's also

I've spent the last few days aggressively parallelizing some Rust code with crossbeam, and it's really just... painless (once you're used to Rust). Rust actually understands data races, and it grumbles at me until my code is

OK, just to back up a step, here's my best argument in favor of automated testing: Virtually nobody just makes a change and ships it users without some kind of testing. Maybe you run your program by hand and mess around with the UI.
