Created June 16, 2018 19:02
relative map based on abstract operations
#!/usr/bin/python3
"""
Draft for a relative ``map`` based on abstract operations
.. function:: map(function, iterable, ...)
.. function:: reify(operation, iterable)
Apply the relative ``operation`` to every element of ``iterable``.
For example, ``reify(relative[0], [(1, 2, 3), range(5), "foobar"])`` returns ``[1, 0, 'f']``.
