One problem is that it does not extend nicely to tables. If you could
write "s:len()", it would be quite reasonable to expect "t:next(k)" to
work as well. However, to have a default metatable for tables has two
drawbacks (at least):

Yes, that's true. The whole system I'm proposing (in the other thread) is for things that don't already have metatables, and at some point I need to address how the two different schemes might be united. I'll think about it more to see if I can find way to make it all work - elegantly.
