Golang中接口内结构体指针的语法错误？怎么回事？

Golang中接口内结构体指针的语法错误？怎么回事？ 有人知道为什么在这个文件中会出现语法错误吗？我在其他文件中为Phone、Email、Person等做过同样的操作都没问题。但不知为何这个文件无法接受指向结构体的指针。

package interfaces

//Go library for decoding generic map values into native Go structures.
//github.com/mitchellh/mapstructure
//Utilities for Go structs
//github.com/fatih/structs
//TODO: Create new Public repo and Combine required source from each of these two
//repos. We need to same for Struct and interface and Convert to/from each as well
//as the methods for getting / working with the field, values list, etc.
/*
func (s *struct) ToMap() Map{interface}
func (Map{interface}) FromMap() *struct

func (s *struct) FillInterface(m Map{Interface})
func (Map{interface}) FillStruct(s *struct)

..Incomplete ...
