Content
Given that def foo(): int; str; bytes; float; int; str; bytes; float can be trivially be rewritten as def foo(): pass I think that benchmark is meaningless. I really don't think we should be making claims like "40% speedup" for such contrived examples. It looks like the speedup is real, but only about 2% speedup overall. The "what's new" should reflect that, IMO.
