(almost) has implicit interfaces Background: I move between Go and C# a lot, and like to compare them Go has implicit interfaces, which means that a type implements an interface iff it satisfies that interface. It’s not declared.

For example, C#’s Stream and StreamReader have identical Read methods – but no Reader interface declared.
