Six

-----

- Issue 32: urllib module wrappings don't work when six is not a toplevel file.

-----

- Issue 31: Add six.moves mapping for UserString.

- Pull request 12: Add six.add_metaclass, a decorator for adding a metaclass to
a class.

- Add six.moves.zip_longest and six.moves.filterfalse, which correspond
respectively to itertools.izip_longest and itertools.ifilterfalse on Python 2
and itertools.zip_longest and itertools.filterfalse on Python 3.

- Issue 25: Add the unichr function, which returns a string for a Unicode
codepoint.

- Issue 26: Add byte2int function, which complements int2byte.

- Add a PY2 constant with obvious semantics.

- Add helpers for indexing and iterating over bytes: iterbytes and indexbytes.

- Add create_bound_method() wrapper.

- Issue 23: Allow multiple base classes to be passed to with_metaclass.

- Issue 24: Add six.moves.range alias. This exactly the same as the current
xrange alias.

- Pull request 5: Create six.moves.urllib, which contains abstractions for a
bunch of things which are in urllib in Python 3 and spread out across urllib,
urllib2, and urlparse in Python 2.

-----

- Issue 21: Add methods to access the closure and globals of a function.

- In six.iter(items/keys/values/lists), passed keyword arguments through to the
underlying method.

- Add six.iterlists().

- Issue 20: Fix tests if tkinter is not available.

- Issue 17: Define callable to be builtin callable when it is available again
in Python 3.2+.

- Issue 16: Rename Python 2 exec_'s arguments, so casually calling exec_ with
keyword arguments will raise.

- Issue 14: Put the six.moves package in sys.modules based on the name six is
imported under.

- Fix Jython detection.

- Pull request 4: Add email_mime_multipart, email_mime_text, and
email_mime_base to six.moves.

-----

- Issue 13: Make iterkeys/itervalues/iteritems return iterators on Python 3
instead of iterables.

- Issue 11: Fix maxsize support on Jython.

- Add six.next() as an alias for six.advance_iterator().

- Use the builtin next() function for advance_iterator() where is available
(2.6+), not just Python 3.

- Add the Iterator class for writing portable iterators.

-----

- Add the int2byte function.

- Add compatibility mappings for iterators over the keys, values, and items of a
dictionary.

- Fix six.MAXSIZE on platforms where sizeof(long) != sizeof(Py_ssize_t).

- Issue 3: Add six.moves mappings for filter, map, and zip.

----------

- Reworked six into one .py file. This breaks imports. Please tell me if you
are interested in an import compatibility layer.
