I'm guessing the issues (from the original mail) are that it does not benefit from the "concision" ascribed to comprehension (though that concision really is mostly when there isn't a mapping and/or filtering method readily available), and that `reduce` moved to `functools` in Python 3

And of course, for this precise expression you could just do this:

>>> ''.join(x.strip() for x in xs)
