On the contrary, I would say that it cleans things up amazingly. As the language currently is, if I want to change one of the default values, I need to specify every single value up to that point. func(5,0,0,NULL,0,true,true,false,NULL,true); func(verbose: true); With named parameters, I can just specify the differences between my function call and the default values.
