Is it ever useful to know what the exception type is in this case? I ask,
because it seems to me that there's no way to recover in this case, and the
only reason for propogation is to give some possibility for a clean exit
instead of an abrubt halt. If you can't recover, then what need is there
for knowing the exception type?
