title: Force import module from Python standard library instead of PYTHONPATH default
body: <p>I have a custom module in one of the directories in my PYTHONPATH with the same name as one of the standard library modules, so that when I <code>import module_name</code>, that module gets loaded. If I want to use the original standard library module, is there any way to force Python to import from the standard library rather than from the PYTHONPATH directory, short of renaming the custom module and changing every reference to point to the new name?</p>
