I see the use for generics all the time. I came from Ruby, where we have enumerable so you get standard constructs like map, find, first, last, each_cons, etc.

I see the use for generics all the time. I came from Ruby, where we have enumerable so you get standard constructs like map, find, first, last, each_cons, etc. Because Go lacks them, people constantly reimplement these things with less intention-revealed code using ad hoc for loops. Ugh. Thus you see very little use of collection pipelining in Go. https://martinfowler.com/articles/collection-pipeline/ https://martinfowler.com/articles/collection-pipeline/ Generics are such a powerful and useful idea. Bring it on.
