another way to think of implicitly satisfy is:

Note

as long as a type has the full set of signatures that an interface defines, the type satisfies the interface

even if the creator of the type doesn’t even know the existence of the interface!

we have:

type MyType struct {
	field string
}
func (m MyType) String() string {
	return field
}

in this example, I just created MyType
and, MyType satisfies Stringer interface
- even when Stringer does NOT exist the code at all!
