AnyEquatable
Provide func isEqual(_: Any, _: Any) -> Bool function which compares values even if they are not Equatable.
AnyEquatable.isEqual("abc", "abc") // true
AnyEquatable.isEqual(1, 3) // false
// Compare not Equatable types
struct NotEquatable {}
AnyEquatable.isEqual(NotEquatable(), NotEquatable()) // false
// Compare different types
AnyEquatable.isEqual(1, "abc") // false
