This module is designed to be used like this:: from future.builtins.disabled import * This disables the following obsolete Py2 builtin functions:: apply, cmp, coerce, execfile, file, input, long, raw_input, reduce, reload, unicode, xrange We don't hack __builtin__, which is very fragile because it contaminates imported modules too. Instead, we just create new functions with the same names as the obsolete builtins from Python 2 which raise NameError exceptions when called. Note that both ``input()`` and ``raw_input()`` are among the disabled functions (in this module). Although ``input()`` exists as a builtin in Python 3, the Python 2 ``input()`` builtin is unsafe to use because it can lead to shell injection. Therefore we shadow it by default upon ``from future.builtins.disabled import *``, in case someone forgets to import our replacement ``input()`` somehow and expects Python 3 semantics. See the ``future.builtins.misc`` module for a working version of ``input`` with Python 3 semantics. (Note that callable() is not among the functions disabled; this was reintroduced into Python 3.2.)
