Hmm, it's close, but by not allowing keywords it's going to be very unsightly for something with optional arguments. Additionally, we're going to need to restrict the output from any function like this to values we can serialise as text (basically, repr plus a few custom handlers for things like model instances), and getinitargs doesn't enforce that either.
