Kotlin can be great, but the amount of syntactic sugar available very easily baits undisciplined devs into writing very concise, wholly incomprehensible code. I’d pick it for a project where I know and trust every dev who will work on it, but not for something that might get a lot of touches from a lot of people.

I’ve heard of that one but just can’t find the time to try it out. What uses is it best for?
