I guess the Lua authors have already considered this possibility (because it's so simple to implement), but probably rejected it.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.
