New description:
The Py2 builtin function {{{reduce()}}} is available in Py3 as
{{{functools.reduce()}}}.
The tool 2to3 adds {{{from functools import reduce}}}.
From the [[https://docs.python.org/2.7/library/functools.html#module-
functools||Python 2.7 documentation]]: [[br]]
functools.reduce(function, iterable[, initializer])[[br]]
This is the same function as reduce(). It is made available in this module
to allow writing code more forward-compatible with Python 3.
New in version 2.6.
This ticket is tracked as a dependency of meta-ticket ticket:16052.
