The only pragmatic argument that I could understand is the hard-wiring “issue”; which IMO is not part of FP and neither OOP but just a consequence that explicit intents are simpler than implicit intents.
I understand that this is to introduce to a novelty approach that Multix offers with cats.
But to be fair, not as sofisticate as Multix, Dependency Injection tries to tackle the hard-wiring constraints of imperative.
What I take from FP is Composition rather than Chaining, which much more flexible than the OOP counterpart, inheritance.
I was expecting to learn something new but I just jump in a spooky vocabulary that rather teach me something just waste my time.
The point stand, Multix might be a fabulous approach in coding, but this article failed to give any practical introduction to it, while claiming his superiority in something that totally didn’t resonate with me.
If your mission is getting Multix adopters I will invite you to shift your focus from language/tone/academical complexity; to something more simple, what does it solve?
