> No, an error implements the error interface. It means that it can be a value of any type that implements the constraint of having an Error method.
It doesn't matter what a value implements if you don't test its content by type. Std lib errors are meant to be tested by value, not by type. It has nothing to do with interfaces again. When you get a std lib error in order to know what error it is you compare it to an exported value, not its type. I don't know why you keep on insisting on interfaces that's not the core of the issue here.
