I have considered doing that, but I haven't yet had the time to actually get
it done. I would like to use a provided exception list and, if one is not
provided, look for a nested exceptions type.

By the way, I don't know if I have said this yet or not, but one of my
primary motivations for tinkering around with this in the first place is
sheer laziness. I don't like to write more than one catch block if I can
absolutely help it.
