A similar problem applies to Go, just inverted. Take iteration. The vast majority of use cases for iterating over containers are map, filter, reduce. Go doesn't have these functions. That's very simple! All Go developers are aligned here: just use a for loop. There's no room for "10% of concepts corners", there's just that 1 corner.

But, for loops get tedious. So people will make helper functions. Generic ones today, non-generic in the past. The result is that you have a zoo of iteration-related helper functions all throughout. You'll need to learn those when onboarding to a new code base as well. Go's readability makes this easier, but by definitions everything's entirely non-standard.
