See example below. This compiles and runs on HTML5, GLFW and XNA (with a C# compile warning) but fails on Flash.

The Flash error can be resolved by not repeating the Blah method declaration. It also doesn't occur if the instance reference is declared as the class type rather than the interface type.

I would expect all targets to error on the override at the Monkey level or for them all to work.

Import mojo

Interface ITest
    Method Blah:Void(val:Int)
End

Interface ITestPlus Extends ITest
    Method Blah:Void(val:Int)
    Method BlahPlus:Void(val:Int)
End

Class TestPlus Implements ITestPlus
    Method Blah:Void(val:Int)
        Print "Blah: " + val
    End
    Method BlahPlus:Void(val:Int)
        Print "BlahPlus: " + val
    End
End

Function Main()
    Local a:App = New App()
    
    Local tp:ITestPlus = New TestPlus()
    tp.Blah(1)
    tp.BlahPlus(2)
End
