Acts as a context manager. Saves the state of sys.modules and restores it
after the 'with' block.
Use like this:
>>> from future import standard_library
>>> with standard_library.hooks():
... import http.client
>>> import requests
For this to work, http.client will be scrubbed from sys.modules after the
'with' block. That way the modules imported in the 'with' block will
continue to be accessible in the current namespace but not from any
imported modules (like requests).

Pass a (potentially dotted) module name of a Python 3 standard library
module. This function imports the module compatibly on Py2 and Py3 and
returns the top-level module.
Example use:
>>> http = import_('http.client')
>>> http = import_('http.server')
>>> urllib = import_('urllib.request')
Then:
>>> conn = http.client.HTTPConnection(...)
>>> response = urllib.request.urlopen('http://mywebsite.com')
>>> # etc.
Use as follows:
>>> package_name = import_(module_name)
On Py3, equivalent to this:
>>> import module_name
On Py2, equivalent to this if backport=False:
>>> from future.moves import module_name
or to this if backport=True:
>>> from future.backports import module_name
except that it also handles dotted module names such as ``http.client``
The effect then is like this:
>>> from future.backports import module
>>> from future.backports.module import submodule
>>> module.submodule = submodule
Note that this would be a SyntaxError in Python:
>>> from future.backports import http.client

A context-manager that prevents standard library modules like configparser
from being imported from the local python-future source folder on Py3.
(This was need prior to v0.16.0 because the presence of a configparser
folder would otherwise have prevented setuptools from running on Py3. Maybe
it's not needed any more?)
