The :mod:`new` module allows an interface to the interpreter object creation
functions. This is for use primarily in marshal-type functions, when a new
object needs to be created "magically" and not by using the regular creation
functions. This module provides a low-level interface to the interpreter, so
care must be exercised when using this module. It is possible to supply
non-sensical arguments which crash the interpreter when the object is used.
The :mod:`new` module defines the following functions:
.. function:: instance(class[, dict])
This function creates an instance of *class* with dictionary *dict* without
calling the :meth:`__init__` constructor. If *dict* is omitted or ``None``, a
new, empty dictionary is created for the new instance. Note that there are no
guarantees that the object will be in a consistent state.
.. function:: instancemethod(function, instance, class)
This function will return a method object, bound to *instance*, or unbound if
*instance* is ``None``. *function* must be callable.
.. function:: function(code, globals[, name[, argdefs[, closure]]])
Returns a (Python) function with the given code and globals. If *name* is given,
it must be a string or ``None``. If it is a string, the function will have the
given name, otherwise the function name will be taken from ``code.co_name``. If
*argdefs* is given, it must be a tuple and will be used to determine the default
values of parameters. If *closure* is given, it must be ``None`` or a tuple of
cell objects containing objects to bind to the names in ``code.co_freevars``.
.. function:: code(argcount, nlocals, stacksize, flags, codestring, constants, names, varnames, filename, name, firstlineno, lnotab)
This function is an interface to the :cfunc:`PyCode_New` C function.

.. function:: module(name[, doc])
This function returns a new module object with name *name*. *name* must be a
string. The optional *doc* argument can have any type.
.. function:: classobj(name, baseclasses, dict)
This function returns a new class object, with name *name*, derived from
*baseclasses* (which should be a tuple of classes) and with namespace *dict*.
