Scala Collections: Why not?


Paul Phillips, co-founder of Typesafe


Yes, complexity all over the place. The small project I have with Scala was done in 2017 and back at that time I was very eager to start using Functional Programming Languages.

I find really complicated to manage all the type system required. It has little logic to me. So, I left that out there.


When I’m working on a problem, I never think about beauty. I think only how to solve the problem.

But when I have finished, if the solution is not beautiful, I know it is wrong.

He wrote a least 3 million lines of code in Scala.. what?..

Is Scala too complex? Yes

All manner of behavior is ill-defined, which means users have to program defensively and compiler team cannot optimize


  1. Make beautiful code

  2. Does not let implementation details infest everything
