Other Language Changes
======================
Some smaller changes made to the core Python language are:
* The syntax for set literals has been backported from Python 3.x.
Curly brackets are used to surround the contents of the resulting
mutable set; set literals are
distinguished from dictionaries by not containing colons and values.
``{}`` continues to represent an empty dictionary; use
``set()`` for an empty set.
>>> {1,2,3,4,5}
set([1, 2, 3, 4, 5])
>>> set()
set([])
>>> {}
{}
Backported by Alexandre Vassalotti; :issue:`2335`.
* Dictionary and set comprehensions are another feature backported from
3.x, generalizing list/generator comprehensions to use
the literal syntax for sets and dictionaries.
>>> {x:x*x for x in range(6)}
{0: 0, 1: 1, 2: 4, 3: 9, 4: 16, 5: 25}
>>> {'a'*x for x in range(6)}
set(['', 'a', 'aa', 'aaa', 'aaaa', 'aaaaa'])
Backported by Alexandre Vassalotti; :issue:`2333`.
* The :keyword:`with` statement can now use multiple context managers
in one statement. Context managers are processed from left to right
and each one is treated as beginning a new :keyword:`with` statement.

A Distutils setup can now specify that a C extension is optional by
setting the *optional* option setting to true. If this optional is
supplied, failure to build the extension will not abort the build
process, but instead simply not install the failing extension.
