My opinion is that the "this is obvious" comments dilute the value of
the other comments.  If *everything* has a comment of some sort, you
lose the ability to pick out the important ones, and instead learn to
filter them all out.

As for the randomly picking of values, that's worthy of a FIXME
comment ;-)
