Hey, I count as a young programmer and I use docstrings and comments
all over my code! Sometimes my style could be called 'comment-first'
(and then code). :)

Young programmers have heard about Extreme Programming too, you
know. Not that this was invented with Extreme Programming; they're
just the most popular bunch that articulated and promoted this
approach. They may be in a long line of such groups, but I wouldn't
know that; before my time, young programmer and all. :)
