So, is this work?
=== code begin ===
type
IFoo = interface
function Execute: IFoo;
end;
TFooHelper = type helper for IFoo
procedure Something;
end;
TFoo = class(TInterfacedObject, IFoo)
public
function Execute: IFoo;
end;
var
F: IFoo;
begin
F := TFoo.Create;
F.Execute.Something;
end;
=== code end ===
