Ah! No, that is not possible, because interfaces (and other types) are not
first-class objects in Go like they are in some other languages (such as
Python). You can work around it, to some extent, by passing a zero-valued
instance of such an interface (e.g. PrintInterface(A{})) and using some
reflection magics to do what you need based on the reflect.Type and similar.
That's how a number of libraries like Resty determine how to e.g. deserialize
JSON to a specific type requested by users. It's got its warts, but it works.
