proposal: natively built-in enumerated types syntax for Go

[duc18020319]

Go version
go version go1.24.0 windows/amd64

What did I do and see happen?
Normally, if an enumerated type is created in Go (using a code snippet in Web):

package main

import "fmt"

const (
	ENUMERATED_VALUE_1 = iota
	ENUMERATED_VALUE_2 = iota
	ENUMERATED_VALUE_3 = iota
	ENUMERATED_VALUE_4 = iota
)

, which doesn't have a name.

What did I expect to see?
Enumerated types (enums) can be declared natively by the language like this:

type Enumeration enum {
	ENUMERATED_VALUE_1,
	ENUMERATED_VALUE_2,
	ENUMERATED_VALUE_3,
	ENUMERATED_VALUE_4,
}

, rather than using constants and 'iota', like enums in C.
