The reason I have to do this, and why $! was so attractive is that I
have many rescue blocks scattered throughout the code, which Im trying
to fix up, but I dont want to do them all at once, so just seeing the
last exception, was going to be helpful. I have another work around
that isnt as nice as $! appeared to be, but it does enough for what I
need

Thanks for all your help
