Assuming join = lambda *args: ''.join(map(str, args))
1. Friendly for people coming from other languages (Perl/shell). Same reason

2. Less quotes and commas for the terminally lazy.
3. More flexible for data-driven use. Either the template or the
dictionary can be data rather than hard-wired into the code.
