Yeah no, that criticism of Haskell is nonsense.

It wasn’t intended as criticism of Haskell at all, I love that language. I have a whole bunch of open source Haskell projects under my name.

It was intended as a criticism of the article, that its whole assumption “FP == making invalid states impossible to represent” is incorrect.

I recognize that it’s very much possible to embrace chaos with Haskell, and I should probably have worded that better.

Utterly ridiculous.

In Haskell you can “embrace chaos” exactly as much as you desire. It’s a general purpose programming language.
