I have a question about the following code-snippet:
type I interface {
DoSomething()
}
type F func()
func (f F) DoSomething() {
f()
}
func A() {
fmt.Println("A")
}
func B() {
fmt.Println("B")
}
func test() {
var _a F = A
var _b F = B
var a I = _a
var b I = _b
if a == b { // 2. No compile error but panic
// Code
}
}
It seems to me, that I can break the type system with simple assignments.
I do not propose that functions should be comparable. My questions are:
- Why are interfaces comparable by default?
- Why is it not possible to mark an interface as comparable resp. not
comparable?
- Why is it not possible do define user defined-equality?
- What is the motivation in this language design?
Thanks
Stephan
