Every time I'm going to solve some interesting programming problem, implement a network layer, a collection with different types of cells and so on, PAT (protocol with associated type) is the first thing that comes to mind, it'd be awesome to implement it this way, I tell myself. Nevertheless, it sucks when Sequence or saving to a variable happens. But I'm not upset - googling "Swift type erasure", implementing _Box, AnyFoo and I'm happy again, not today though...
What I'm talking about? So, if you've felt yourself in the same situation, try thoughtfully reading this article. And maybe next time you won't spend much time on this.

I always prefer writing ==

for bool comparison rather than ! for better readability, but ... oh, common, it dramatically slower.https://twitter.com/nicklockwood/status/1324491275291295749
