I'm not sure I buy that. An assert is saying that something
should never happen. If it does happen, either it's going
to lead to an exception further down the track, or produce
incorrect results. In the first case, you've failed to
shield the user from exceptions; in the second, better to
log an exception than silently pretend nothing has gone
