"""
A resurrection of some old functions from Python 2 for use in Python 3. These
should be used sparingly, to help with porting efforts, since code using them
is no longer standard Python 3 code.
This module provides the following:
1. Implementations of these builtin functions which have no equivalent on Py3:
- apply
- chr
- cmp
- execfile
2. Aliases:
- intern <- sys.intern
- raw_input <- input
- reduce <- functools.reduce
- reload <- imp.reload
- unichr <- chr
- unicode <- str
- xrange <- range
3. List-producing versions of the corresponding Python 3 iterator-producing functions:
- filter
- map
- range
- zip
4. Forward-ported Py2 types:
- basestring
- dict
- str
- long
- unicode
