I think it helps Luca and many others (including myself) if there is a
reference of the difference between 2.7 and Python 3.3+.
There are PEPs and books, but is there any such long list of references?
If not, should we start investing in one? I know the basic one such as
xrange and range, items vs iteritems, izip vs zip that sort of uniform
syntax/library inclusion difference.
If there is such reference available?
