+
+Return lambdas that use the iteration variable as a default argument
+
+    >>> items = {(lambda i=i: i) for i in range(5)}
+    >>> {x() for x in items} == set(range(5))
+    True
+
+Same again, only this time as a closure variable
+
+    >>> items = {(lambda: i) for i in range(5)}
+    >>> {x() for x in items}
+    set([4])
+
+Another way to test that the iteration variable is local to the list comp
+
+    >>> items = {(lambda: i) for i in range(5)}
+    >>> i = 20
+    >>> {x() for x in items}
+    set([4])
+
+And confirm that a closure can jump over the list comp scope
+
+    >>> items = {(lambda: y) for i in range(5)}
+    >>> y = 2
+    >>> {x() for x in items}
+    set([2])

+We also repeat each of the above scoping tests inside a function
+
+    >>> def test_func():
+    ...     items = {(lambda i=i: i) for i in range(5)}

summary:
  Update test_codecs to v2.7
Added skips for test failures relating to UTF-32 (issue 2000), IDNA and asian scripts (issue 1066)
but not for UTF-7 and UTF-16 (existing features). test_codecs scores fail/error/skip = 4/4/45.

changeset:   6936:bdf4b0b5f5f7
user:        Jeff Allen <ja...py at farowl.co.uk>
date:        Sat Dec 29 01:06:41 2012 +0000
summary:
  Fixed test failures in charmap codec and UTF-16 use of PyUnicode.
Added a lot of commentary and made arguments optional in charmap.
Changed return type of UTF-16 decode to PyUnicode (because it is).
Now scoring fail/error/skip = 3/2/45 in test_codecs.

summary:
  Skip test unicode-internal codec & add documentation
After much study, it is apparent that the unicode-internal codec exposes CPython
implementation unhelpfully. Our best course is to equate it to UTF-32BE, skipping
the test until we have one of those. Note Python v3.3 deprecates it anyway.

summary:
  Revise UTF-7 codec
This fixes some minor test failures in test_codecs (now passing with 49 skips)
and obviates some skips in (v2.5-ish) test_unicode (now passing with 1 skip).

summary:
  Codec unicode_internal now uses utf-32be.
CPython 3.3 deprecates this codec, which was tied anyway to the CPython
implementation of unicode strings. Some accommodations made in tests to
the Jython approach within test_codecs: now at 16 skips no errors.

summary:
  Closer _io layers top to bottom.
This change affects resource closing in PySstemState so that buffered files left
open by the application are flushed and closed (instead of closed and flushed).
A Java demonstrates that buffered data reaches the disk.
