Hardwire some type error

[issingle]

hardwire Untiy3d's GUI Type,

        private sealed class MTHD_be079e5823b7454890b6cf3fb4ed05ad : MoonSharp.Interpreter.Interop.StandardDescriptors.HardwiredDescriptors.HardwiredMethodMemberDescriptor {

            internal MTHD_be079e5823b7454890b6cf3fb4ed05ad() {
                this.Initialize(".ctor", true, new MoonSharp.Interpreter.Interop.BasicDescriptors.ParameterDescriptor[] {
                            new MoonSharp.Interpreter.Interop.BasicDescriptors.ParameterDescriptor("object", typeof(object), false, null, false, false, false),
                            new MoonSharp.Interpreter.Interop.BasicDescriptors.ParameterDescriptor("method", typeof(System.IntPtr), false, null, false, false, false)}, false);
            }

            protected override object Invoke(MoonSharp.Interpreter.Script script, object obj, object[] pars, int argscount) {
                //here error!
                return new UnityEngine.GUI.WindowFunction(((object)(pars[0])), ((System.IntPtr)(pars[1])));
            }
        }

UnityEngine.GUI.WindowFunction is a delegate.
