"""
This disables builtin functions (and one exception class) which are
removed from Python 3.3.

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.)

This exception class is also disabled:

    StandardError
