Yeah I follow you. I am providing ways of trying to work around the lack of a higher level type class system. As a baseline, I would recommend not jumping outside golang's given type system just because it feels inconvenient for the programmer. That means you don't get to write a generic method for, for instance, all integers. Too bad :P This means the programmer does have to do more work, but the type system is always strictly enforced. That is better in my opinion.
