I don't have a sense that this could be turned into a new metamethod
for 5.4. It's just a solution that has worked well for me and has
persisted to work well and not smell... yet.

I think that it would be useful in a library like luaproc, which could
specify the expected behavior of such a method and provide a default
__serialize methods  that would probably work for most cases.
