Bug 19494 – [REG 2.080.0][objc] interface `main.NSObject.Class` conflicts with interface `main.NSObject.Class`

The following code fails to compile using 2.080.0 or later: extern (Objective-C) interface NSObject { extern (Objective-C) interface Class {} } The error message is: Error: interface `main.NSObject.Class` conflicts with interface `main.NSObject.Class` The issue is that when Objective-C class methods were implemented the type of the metaclass was accidentally exposed as the "Class" member inside every Objective-C interface.
