I realize that and agree.  In this case, though, it actually looked to
me like the regex was the better way and that maybe the "why use regex?"
was -- this time -- almost a knee jerk in the other direction.

Personally, I would probably have done a .read(), then used .find() to
get the locations of the "!" and "end" and then just taken a slice out
of the string to accomplish the same thing... but I think maybe the
regex would _still_ have been easier this time.
