From the screencast it looks like they altered Ruby syntax by adding named parameters to conform with Obj-C's way of specifying prototypes. I guess this is a trade-off for the fact that Obj-C has some unusual syntax that has no real analog in Ruby -- if you've ever tried developing with PyObjC you'll be familiar with how odd it looks.
