I'm going to go against the HN current opinion but I hate Scala. I worked for a few months on some Scala projects, the language is way too complex (the opposite of Go, they add whatever feature they think is cool) is poorly documented and readability is difficult as well. It looks like a mix of Perl and functional languages.

I hate it as well. I think it's a poorly designed language. The syntax is a mess (underscore...), the operator overloading make people overload silly operators which make code unreadable from an outside programmer. I could go on...

I prefer Kotlin which imho fix almost every bad design decisions from Scala.

If underscores and operator overloading are the biggest criticisms you have of Scala, then we're doing pretty well. For what it's worth, I think Scala has quite a large grammar that means it takes a while to learn, but once that's over it's not particularly difficult to read or to write.

Can you elaborate as to what Kotlin fixes compared to Scala?
