Issue Description:

Snippet:

import Foundation
let a = NSNumber(0)
let b = NSNumber(false)
let c = (a == b)
let d = (AnyHashable(a) == AnyHashable(b))

On macOS we get c = true, d = false.
On Linux we get c = true, d = true.

I don’t know who is right.
It feels to me (a == b) (and it’s AnyHashable variant) should both be false because the numbers were not created with the same type.
