Dan is talking about per-function descriptions in ChangeLog entries, not in
the source code.

Indeed, we try to avoid adding comments as much as possible since comments
tend to get out-of-date very quickly, we don't want to be spending all our
time updating comments. Instead, we try to refactor code so that code is
self-evident or add assertions to codify the comments.
