This is just a "would be nice" sort of post right? The main feature I'd want (list comprehensions) seems to be just a single programmer's guess at an upcoming feature with no real evidence.
Pay close attention to the "status" listed under each header. Some of these features have already landed in master, and others are still in various states of proposal. The author links to the official RFC for most of the proposed features.
I'm not sure if the list comprehensions feature has made it past the mailing list though.
