I guess that subclassing the class for parametric 2d curves should be sufficient. Then just hardcode the range for 't' (be sure to use a Dummy and not a Symbol for it). Concerning `list(args[0].arbitrary_point())` I do not know why it does not work. Probably something was changed and this code is simply broken now as there are no tests for it. I guess the author meant to write `args[0].arbitrary_point().args` in order to get the parametric expressions.
