yeah the issue honestly is how much someone else has to read to understand your code. it’s weird because the whole article is about making readable code for the next person and he never stops to address the fact that leaving 10x as much code to read might also make life more difficult.

I feel like he just wanted to make a point about how it’s nice to make types immutable and suggest other techniques can be worth implementing too, which I agree with, but honestly his premise is a trainwreck.
