I tried it out at some point, and it's a nice language I guess, but man, the compile times. It's not worth it, just learn C or C++.

And your productivity on your team plummets as a result.

Rust also has slow build times [0], but it didn't stop people from using it.

well.. certainly it has stopped 'some' people from using it though for many the compilation costs are worth it

If the rust syntax and borrow checker wasn't masochistic enough...

If compiling 7 lines of code in release mode takes few minutes in Rust, just like it does in Crystal (I don't know exactly how long, I got bored and gave up, so it's possibly more), then I wouldn't touch that language with a ten foot pole either. It's fine to make trade-offs, it's just not a trade-off I'm personally willing to make. As to the productivity thing, it's debatable I guess.

It doesn't, a few seconds in debug mode, maybe 10-15s for release. I actually have a couple scripts that use `crystal run` instead of a compiled binary.

Minutes? Now way! I have a Crystal code base with 10s of thousands of lines and it takes like 10-30 seconds.

The solution is to start breaking up the monolith so you only compile sections at a time.

So when did you start using a Nokia 3310 as your dev machine?
