@noelrap 'crystal' is just way too hard to spell 😂

@noelrap longer dev cycles, making developers more money for doing the same work

@noelrap Editor tooling for me, with performance a distant second.

Pre-execution validation is nice but I actually also kind of like that the absence of that guarantee means you really have to have good test coverage to avoid silly runtime errors.

@noelrap API documentation.

@noelrap For me it's about tightening up the feedback loop.

I want the type checker to tell me that assumptions I've made are wrong and that, for example, the method I've been testing with a symbol parameter is going to be passed a string from the API layer. It sucks to only find that one out in production when the alerts start going off.

Stupid mistakes like that should be surfaced as soon as I've finished typing the method call/signature.

@noelrap writing less tests. Writing only business logic tests.
