def release_local(local):
    """Releases the contents of the local for the current context.
    This makes it possible to use locals without a manager.

    Example::

        >>> loc = Local()
        >>> loc.foo = 42
        >>> release_local(loc)
        >>> hasattr(loc, 'foo')
        False

    With this function one can release :class:`Local` objects as well
    as :class:`StackLocal` objects.  However it is not possible to
    release data held by proxies that way, one always has to retain
    a reference to the underlying local object in order to be able
    to release it.
