It's extremely messy and annoying to work with, to do the same thing you'd do by walking one step in Haskell you have to do five somersaults in Scala. It can't be fixed, and the Scala community thinks fixing it means hiding it behind fifty layers of fragile abstractions.

This is not really about typesystem differences. So, probably not everything at an expert level?

what is wrong with you?

Every time I see a long list of technologies I truly wonder what level of knowledge the claimant assumes. In most of the cases breadth replaces depth.

there's a time and a place, this is clearly not it.

Why not?

this isn't a comments section for an article, it's a reverse job posting by a human. you appear to be taking pot shots at the commenter with a stated goal of exposing their lack of depth in one of the technologies they listed in their posting. you don't appear to be making a good faith attempt to hire or interview this person. in the context of a "Who is hiring" post, this is antisocial behavior and rude. additionally, nowhere in the post was any sort of claim made that the author is an expert in anything.
