You will never obtain a deep understanding of functional programming by using Scala. You'll simply never be able to think those thoughts, even though you are otherwise capable.

Having switched from Scala to Haskell and Idris, I can relate to this statement. There’s stuff that requires some additional boilerplate and hoop jumping in Scala that just works in Haskell (once you turn on a particular language extension)

This noise can make it difficult to see what is going on. Hence, in many cases where people found an unintuitive encoding of a feature in Scala, it’s useful to look at how it’s done in Haskell. Haskell is the source and inspiration of many ideas that appear in the Scala world.

Well, expect to be accused of, "trying to use Scala as if it were Haskell." No matter the fact that nobody ever tries it, nor that it is a ridiculous idea, this description still persists today. I last saw it a few days ago.

Oh I’m deaf to that accusation, because — even given the opaqueness of many of the encodings — I’ve seen and reaped the benefits of Haskell-inspired pure functional programming

It's pretty funny, actually :)
