And when you finally get them, you'll wonder how you ever lived without :-)

Yet having moved from (primarily) Java to (primarily) Go I find I don't miss them.

I had them (Java and C#) and I am happy Go does not have them. I feel like most people just miss them for collections and abuse them in other instances.

And for collections Go has other tools (like generator if you really want to). Overall in the 2ish years of writing Go, I only missed them when I was learning the language coming from years of Java.

When you need to switch from native maps to sync.Map, you not only have to give up type safety but rewrite all your calling code. Codegen doesn't help because you are not one of the people allowed to overload those operators.

It is more that you code around the lack of generics.

Interfaces: same API, different source code. Generics: different APIs, same source code.

This is why Go needs to have generics.

A bit like saying if you know you won’t have a hammer, you’ll instead bring a drill, a screwdriver, and screws. But sometimes it’s nice to be able to nail things together.
