Yes. You have to understand how "fmt.Print," etc., handle types with String() methods. From the docs:
package fmt - 5. If an operand implements method String() string, that method will be invoked to convert the object to a string, which will then be formatted as required by the verb (if any). package reflect - func (Value) Elem <http://localhost:6060/src/reflect/value.go?s=25679:25706#L800> func (v Value <http://localhost:6060/pkg/reflect/#Value>) Elem() Value <http://localhost:6060/pkg/reflect/#Value> Elem returns the value that the interface v contains or that the pointer v points to. It panics if v's Kind is not Interface or Ptr. It returns the zero Value if v is nil. func (Value) String <http://localhost:6060/src/reflect/value.go?s=55738:55768#L1847> func (v Value <http://localhost:6060/pkg/reflect/#Value>) String() string <http://localhost:6060/pkg/builtin/#string> String returns the string v's underlying value, as a string. String is a special case because of Go's String method convention. Unlike the other getters, it does not panic if v's Kind is not String. Instead, it returns a string of the form "<T value>" where T is v's type. The fmt package treats Values specially. It does not call their String method implicitly but instead prints the concrete values they hold.
