So, there certainly won't be any restriction on

implementing class.

Hi Jonathan,
interesting : this snippet compiles.

interface IBindingList {
                
        @property bool AllowEdit();


class A : IBindingList {
        private bool _allowEdit;

        @property {
                bool AllowEdit() { return _allowEdit;   }
                bool AllowEdit(bool enable) { return _allowEdit = enable; }
        }       
}

But this one NOT.

interface IBindingList {
                
        @property bool AllowEdit();
        @property bool AllowEdit(bool enable);
}
class A : IBindingList {
        private bool _allowEdit;

        @property {
                bool AllowEdit() { return _allowEdit;   }
        }       
}
IMO this is bad design.
