from functools import partial, reduce
from itertools import  cycle
from operator import itemgetter

compose = lambda *funcs: lambda x: reduce(lambda y, f: f(y), reversed(funcs), x)
zip_apply = lambda fs, values: (f(value) for f, value in zip(fs, values))
wrap = lambda x: [x]

unpack = partial(zip_apply, tuple(map(itemgetter, (0, 2, -2))))
easy_unpack = compose(tuple, unpack, cycle, wrap)

You're right, with such implementation the function name probably should be notsoeasy_unpack :-) The <a href="https://py.checkio.org/mission/bigger-price/publications/flpo/python-3/composition-of-functions/">"Composition of Functions" solution for Bigger Price task</a> is based on a similar approach but it's just a bit more puzzled ;-)
