I would like to support your comment and add that I enjoy these articles because I like programming languages and thinking about program execution.

However, I think what delibes is getting at is that this is article exhibits a classic trigger for most developers because it starts with naming some language (i.e. Haskell) and then it is filled with assertions that are always "What If": what if your language doesn't support sum types or recursion or algebraic data types or ... Most devs are looking for practical applications for their language of choice so there is a natural inclination toward a critical comparison of "their" language and "my" language.

But we should follow Twisol here and not read this article as "language X is better than language Y" or, more precisely, "throw out unnecessary features from language X because you can still perform some task Z".

Just take the article for what it is: a great "explanation"[1] of the relation between mathematical foundations and language features or characteristics. This article isn't some heretical tantrum so just sit back and enjoy the learning.

I have noticed a lot of random hate against Haskell devs specifically, see https://twitter.com/catachresthetic/status/13106325659556044... for another example.
