I meant to imply that (1) would be something implemented inside the
interpreter because that behavior isn't defined in the spec. (Indeed,
the spec doesn't require that anything is implemented array-like as
long as Lua scripts can treat it as a sequence.) I realized a while
after I sent the message that I didn't make this clear.
