[go-nuts] method receiver basics

I am wondering about why have methods & receivers while we have function
that take parameters? Is it convenience in case of interface or in general.

Like for this example: http://play.golang.org/p/Xyj8Z7Isv4

We can just live with GetValue2() method and compiler accepts t.GetValue2()
injecting t wherever it finds in function parameter at compile time and
also make decision about pass by reference or value.


type Type1 string

func (t *Type1) GetValue() string{
return fmt.Sprint("Value is ",*t)
}

func GetValue2(t *Type1) string{
return fmt.Sprint("Value is ",*t)
}


func main() {
var t Type1 = "type1val"
fmt.Println(t.GetValue()) // if we have GetValue2 only then we can make it
compile like: t.GetValue2()
fmt.Println(GetValue2(&t))
}
