- convert print, StringIO, except as, octals, izip - convert print statement to print function - convert StringIO to six.StringIO - remove usage of csv reader in Spec, in favor of simple regex - csv reader only does byte strings - convert 0755 octal literals to 0o755 - convert `except Foo, e` to `except Foo as e` - fix a few places `str` is used. - may need to switch everything to str later. - convert iteritems usages to use six.iteritems - fix urllib and HTMLParser - port metaclasses to use six.with_metaclass - More octal literal conversions for Python 2/3 - Fix a new octal literal. - Convert `basestring` to `six.string_types` - Convert xrange -> range - Fix various issues with encoding, iteritems, and Python3 semantics. - Convert contextlib.nested to explicitly nexted context managers. - Convert use of filter() to list comprehensions. - Replace reduce() with list comprehensions. - Clean up composite: replace inspect.ismethod() with callable() - Python 3 doesn't have "method" objects; inspect.ismethod returns False. - Need to use callable in Composite to make it work. - Update colify to use future division. - Fix zip() usages that need to be lists. - Python3: Use line-buffered logging instead of unbuffered. - Python3 raises an error with unbuffered I/O - See https://bugs.python.org/issue17404
