It does nowadays. Once upon a time, Python didn't have proper closures,
and argument defaults, evaluated at function-definition time, were the
only way of capturing data from the surrounding environment. You may be
confusing `mediocre' with `old-fashioned', and `a hankering towards
cleverness' with `wanting to run code on old Python interpreters'. This
last may be because the relevant code was written back when those `old'
interpreters were shiny and new.
