Hi,
Just a couple of friendly notes / impressions: I couldn't help but notice
how many new gramars, or additions would need to be added to the language
in order to support a feature aiming to be simple, in a language where one
of the top driving goals it to be as simple as possible. Also no built in
types would be able to satisfy both of the constraints, because you can't
declare methods on builtin types in order to satisfy the interface.
Lastly, remember this code:
package main
import (
"fmt"
)
type word string
func main() {
var x word = "hello"
var z string = x
}
Wont compile, with the message:
"cannot use w (type word) as type string in assignment"
But:
package main
import (
"fmt"
)
type word string
func main() {
var w word
w = "What am I?"
var z string
fmt.Printf("w is a: %T. z is a %T.\n", w, z)
Does, and prints out:
w is a: main.word. z is a string.
( Runnable example: https://play.golang.org/p/wek23WOXNEJ )
Because they are two different things, It would be akin to attempting to
assign an int value to a var of type uint16.
