Whoa! I had just written the equivalent code for NilClass a few days
ago, and was going to work on generalizing it. Check that one off the
list! --But your's doesn't work for immutables like NilClass. It's a a
bit more difficult in these cases. Have a clever solution? In any case
I'll take this and what I have and add it to Facets.

Very cool. This goes along way toward making core extensions safe.
