            if (arguments.Count == 0 || parameters.Length == 0)

                var elementType = lastParam.ParameterType.GetElementType();
                if (overflowingArgs.Any(arg => arg.Type != elementType && !arg.Type.IsSubclassOf(elementType)))

            // class to proxy to methods from different source classes.

            // {
            // If the param is a delegate it needs to be replaced with a string which
            // will be used to find the 'real' delegate in the jish_internal scope.

            // }
            // Else add standard inline arg
            gen.Emit(OpCodes.Ldarg, i + 1);
