Scala punching the air rn
It's like French poetry.. So much elegance. An no effect system BS. Just like Martin Odersky intended it to be!
Yes, but also a bit of a torture to read code in it..
Too far: there are several dialects one can use with it e.g., I can speak Haskell with Scala grammar. Unlike with Java there is no central Scala dialect, so reading/maintaining a Scala codebase can be a challenge.
Too close: its type system, as advanced as it is, is still stuck in Java’s inheritance and all its limitations. Traits, for example, are not runtime components, they dissolve into the hosting class’ single object, giving up the independent identity and flexibility of runtime configured composition. And the Scala 3 `exports` feature that departs Java’s inheritance is just forwarding, not true delegation; it is the inverse of traits: it trades self identity for independent identity (no late-bound self that comes free with impl inheritance).
I prefer extension methods for what Scala implicits do [1], [2]. The only part that is lacking with extension methods is to be able to extend a type to implement an interface, e.g. Comparable, but you can create extension methods that return anonymous objects [3].

Thankfully, not in the core language :)
There are just too many ways to use Scala, and everyone thinks they're doing it "idiomatically".
