Functional
----------
Utils for functional programming.
.. py:function:: pydu.functional.compose(*funcs)
Compose all functions. The previous function must accept one argument,
which is the output of the next function. The last function can accept
any args and kwargs.
compose(f1, f2, f3)(\*x) is same to f1(f2(f3(\*x))).
>>> from pydu.functional import compose
>>> def f1(a):
... return a+1
...
>>> def f2(a, b=2):
... return a+b
...
>>> compose(f1, f2)(1, b=3)
