- """This module provides functions that will be builtins in Python 3.0,
- but that conflict with builtins that already exist in Python 2.x.
- Functions:
- hex(arg) -- Returns the hexadecimal representation of an integer
- oct(arg) -- Returns the octal representation of an integer
- ascii(arg) -- Same as repr(arg)
- map, filter, zip -- Same as itertools.imap, ifilter, izip
- The typical usage of this module is to replace existing builtins in a
- module's namespace:
- from future_builtins import hex, oct
- """
