This is one of my concerns. Java clearly suffers from having generics bolted on much later and the underlying type system would be different if generics were contemplated from the start. Will Go have similar problems when they eventually add generics?
Actually the Go team has mentioned what happened with Java is a reason why they have not added generics, they have said they wont add them unless they are 100% certain that they are happy with the design and that they will not damage the language.
