.. function:: re_find(regex, s, flags=0)
.. function:: re_test(regex, s, flags=0)
.. function:: re_iter(regex, s, flags=0)
.. function:: re_all(regex, s, flags=0)


.. function:: re_finder(regex, flags=0)

    Returns a function that calls :func:`re_find` for it's sole argument. It's main purpose is quickly constructing mapper functions for :func:`map` and friends.

    See also :ref:`extended_fns`.


.. function:: re_tester(regex, flags=0)

    Returns a function that calls :func:`re_test` for it's sole argument. Aimed at quick construction of predicates for use in :func:`filter` and friends.

    See also :ref:`extended_fns`.


.. function:: str_join([sep=""], seq)
