>The last time I looked chaining collection operations still required unnecessary boilerplate and was not even the default way to use collections. Did they fix that?

I can't even imagine what you are talking about, so I can't say if they "fixed it" or not.

>Additionally, it seems that moving from lists to a different collection type still involves rewriting your whole code due to the insane idea of using different functions by default

"I did something dumb and now I don't like it". So, don't do it? Why were you using map in the first place?

>I just don't have to deal with any of these design mistakes in Scala

I don't have to deal with them in haskell either. But I do have to deal with the hundreds of other mistakes scala made if I use it.
