Just adding my regular beef about #5, the "everything is an iterator" in regards to the new tuple-unpacking when the wild-card is in the last position: >>> a,b, *c = range(10) >>> a 0 >>> b 1 >>> c [2, 3, 4, 5, 6, 7, 8, 9] >>> type(c) <class 'list'> I've had multiple occasions where I don't care about the rest, yet don't want to consume them. Take for example a, b, *c = itertools.count() It would be perfectly sensible to have it result in >>> a 0 >>> b 1 >>> c count(2) >>> type(c) <class 'itertools.count'> However, because it attempts to consume the iterator before assigning it to `c`, the code will hang until it has completely exhausted memory. As it says further on in #5, "If you want a list, just wrap the result with list." Just a personal pet peeve here. :-) > (The web UI is a bit ~~crap~~ minimialist.

Additionally, classic vi keys of j/k work nicely, as do page-up/page-down, and <space> works to advance a page at a time as well. -tkc -- https://mail.python.org/mailman/listinfo/python-list
