go - Converting map to struct

Question

I am trying to create a generic method in Go that will fill a struct using data from a map[string]interface{}. For example, the method signature and usage might look like:

func FillStruct(data map[string]interface{}, result interface{}) {
    ...
}

type MyStruct struct {
    Name string
    Age  int64
}

myData := make(map[string]interface{})
myData["Name"] = "Tony"
myData["Age"]  = 23

result := &MyStruct{}
FillStruct(myData, result)

// result now has Name set to "Tony" and Age set to 23

I know this can be done using JSON as an intermediary; is there another more efficient way of doing this?
