the behavior has been defined in a way that is compatible with encoding/json. this behavior is as follows: anonymous fields which are structs will have struct fields get field names as if they were directly in the parent struct. anonymous fields which are not structs, or which are interfaces which may or may not point to structs will get field names that correspond to the name of the type the exception to the rules above is that you can always override this behavior by using a JSON struct tag fixes #101
