.. py:class:: DeferredTuple(entry_function, size)

   .. py:attribute:: entry_function


   .. py:attribute:: size


.. py:class:: OrderedSet(*collections)



   Ordered set based on uniqueness of dictionary keys.

   Initialize self.  See help(type(self)) for accurate signature.


   .. py:method:: add(item)


   .. py:method:: update(*args)

      D.update([E, ]**F) -> None.  Update D from mapping/iterable E and F.
      If E is present and has a .keys() method, then does:  for k in E.keys(): D[k] = E[k]
      If E is present and lacks a .keys() method, then does:  for k, v in E: D[k] = v
      In either case, this is followed by: for k in F:  D[k] = F[k]



.. py:function:: complex_to_float(dtype)

.. py:function:: float_to_complex(dtype)

.. py:function:: is_complex_dtype(dtype)

.. py:function:: is_real_dtype(dtype)

.. py:function:: natural_sort(iterable, reverse=False)

   Sort alphanumeric strings naturally, i.e. with "1" before "10".
   Based on http://stackoverflow.com/a/4836734.



.. py:function:: oscillate(iterable, max_passes=np.inf)

   Oscillate forward and backward through an iterable.


.. py:function:: replace(data, selectors, replacement)

   Make an iterator that replaces elements from data with replacement
   when the corresponding element in selectors evaluates to True.


.. py:function:: rev_enumerate(sequence)

   Simple reversed enumerate.


.. py:function:: unify(objects)
