[swift-users] Is this a compiler bug?

[Howard Lovatt via swift-users]

Hi All,

Is this a compiler bug?

struct Box<T> {
    var value: T
    init(_ value: T) { self.value = value }
    /// Unboxing operator.
    static func >> <T>(left: Box<T>, right: inout T?) {
        right = left.value
    }
}

var u: String?
let b = Box("Test")
b >> &u // ERROR: Cannot convert value of type 'Box<String>' to expected
argument type 'Box<_>'

Am I missing something?

Thanks in advance for any help,
  -- Howard.
