This is a very interesting thought. It looks like you are on to something.
However, I would object to the characterization "break down horribly at
run-time". Dynamically typed languages don't let programs "break down
horribly" (in the sense of producing core dumps). To the contrary, a
condition-handling system can provide you features that might be
_exactly_ what you need, and they do so at no cost whatsoever to the
Apart from that, your ideas seem to be a good place to start from.

Hmm, do you happen to have links or references? I would be interested to
hear more about it.
