Based on my background (network and system programming), I'm a bit
suspicious of strings, that is, text. For example, is the stuff that
goes to syslog bytes or text? Does an XML file contain bytes or
(encoded) text? The answers are not obvious to me. Modern computing is
full of ASCII-esque binary communication standards and formats.

Python 2's ambiguity allows me not to answer the tough philosophical
questions. I'm not saying it's necessarily a good thing, but it has its
benefits.
