I want to stress that we want real examples of real code that people want to write, not theoretical ideas for code that people might in theory want to write. Do you have a real program that uses both slices and maps where you would want to have a generic function that prints the keys and values of either a slice or map? When does that come up? When I ask that, I'm looking for a real program, not the idea that somebody somewhere might want to do that. I agree that somebody somewhere might want to do that. But is it an important enough use case that we must handle it in the first attempt at adding generics to the language? When thinking about that, consider that one goal of generics is to permit people to write their own container types, which will by definition not be maps or slices. Should we be looking for some mechanism that can print the keys and values of any container type? Why is it important to handle the cases of slices or maps but not the case of other container types?
