// Interface returns v's value as an interface{}.
// Interface returns v's current value as an interface{}.
// It is equivalent to:
// var i interface{} = (v's underlying value)
// If v is a method obtained by invoking Value.Method
// (as opposed to Type.Method), Interface cannot return an
// interface value, so it panics.
// It also panics if the Value was obtained by accessing
// unexported struct fields.
