It's about Scala, not Haskell, but the gist is the same:
at my company we're giving new candidates a live coding interview where they get one hour to write a very simple application using either Java or Scala. Candidates are free to choose between those languages.
The funny thing is, that candidates who choose Scala are never able to fully finish the assignment. Even though the application is really simple, many don't finish half of it and some even get completely stuck in complex for-comprehensions and what not.
Candidates who choose Java however mostly are able to finish the assignment. The code might not always be the most elegant, but it does what it is supposed to do.
Even though I like Scala a lot, I feel it has the downside that it gives you too many options to do the same thing. This can get in the way when you are simply trying to implement some basic business feature.
That's an interesting question although it's not directly related to the article.
I think it is definitely possible to write Scala code that is easier to read than the same Java code.
However it seems that a large part of the Scala community does not see this as their main objective when writing code.
Sometimes the focus seems to be on writing code as terse as possible, which is not the same as readable.
Or the focus is on making code more generic and abstract, which can be a useful goal depending on the use case, but it's definitely not the same as readable.
