---

In GnoVM, type aliases with the same value are considered equal, while in Go, they are considered different without explicit casting. This leads to inconsistent behavior between Gno and Go.

Example

The following code returns false, false, false in Go, but true, false, false in Gno:

package main

import "fmt"

func check(v1, v2 interface{}) bool {
	return v1 == v2
}

func main() {
	type t1 int
	type t2 int
	v1 := t1(1)
	v2 := t2(1)
	v3 := t2(3)

	fmt.Println("v1, v2", v1, v2, check(v1, v2))
	fmt.Println("v1, v3", v1, v3, check(v1, v3))
	fmt.Println("v2, v3", v2, v3, check(v2, v3))
}
