I want to be able to convert an instance of A in a map to a string.

So if I have something like m := map[string]interface{}{"a" : A("string
field")}

I want to be able to convert it to map[string]interface{}{"a" : "string
field"}

However, I do not want to use something like fmt.Sprintf("%v", m["a"]),
because I don't want ints or the like converted to strings.

Using reflection I'm able to go through and change each field, but since
the map is map[string]*interface{}*, I can't get the type of m["a"]
(reflect.TypeOf(m["a"]) and reflect.TypeOf(m["a"]).Kind() ==
reflect.Interface ).

Does anyone know how to check if an interface field is either a string or
any kind of (type X string) ?
