[trycatch]

I can't disagree more about immature ecosystem. Cats, Scala.js, Shapeless, Akka, reactive streams (Akka Streams, Monix, etc.), Play, Slick and other awesome libs [1] are one of the main reasons why I am using Scala at all. IntelliJ Scala plugin is not perfect, but it understands code much better than, for example, Clion or QtCreator without clang code model, and C++ ecosystem is hardly immature, and of course it's lightyears better than any dynamic language IDE support.

Code complexity though, yeah, it's hard (for me, at least) to grasp ordinary for Scala abstraction-heavy, typeclass-heavy code. I would love to see better code exploration tools for Scala.
