The following currently does not work:
protocol P: class {}
class C: P {}
func foo<T>(t: T) where T: AnyObject {
print("foo")
}
let p: P = C()
foo(t: p) // error: cannot invoke 'foo' with an argument list of type '(t: P)'
It seems to me that this ought to have been allowed, since P is declared as
being a reference type and thus should have been able to satisfy the function’s
requirements.
Is this worthy of writing a language proposal, or would this be considered a
bug that should be sent through the radar system instead?
Thanks,
Charles
