  1. I still wish they'd provide a flag to have groupby sort for you in one operation. I know, copying data and using an iterator is faster, blah blah. However, it's going to be pretty infrequent that the majority of people should want to use groupby without sorting, and if you've got a large enough dataset that it would be problematic, then you're probably using the wrong language anyway. I'd really like to see a test of lazy evaluation versus eager evaluation when you want to convert an entire list anyway.
