agree. when it's 3:42am and you get called in to debug something in a production system in the middle of the night, it's a hell of a lot quicker to visually and mentally parse and digest golang
You think this that functions returning interface{} are easier to debug than functions that return a specific type? Because that's exactly what you are throwing away with generics.
Allowing specification of the element type of a container data structure is not unnecessary abstraction, it's type safety!
