I find generics are overused in most languages. Go will be getting generics to handle the very few situations in which they are a genuine value. But the most common uses cases for generics in other langues are already handled by Go interfaces.

For example Go's `sort.Interface` provides a mechanism to implement generic sort, find and set operations on any type of collection that implements those three methods (Len, Swap, and Less).

I nearly never find myself having to use `interface{}` in my Go code, and those that do usually don't have to, they just don't want to define an appropriate interface.
