I see your point, but I believe that next (and a companion __next)
makes more sense has a general purpose overloadable iterator instead
of ipairs/pairs; the latter could easily be implemented in pure Lua on
top of a counter/next.
Besides, I was just ranting against the "1-based arrays is a
deal-breaker" comment: my point was that the only thing that can't be
changed in Lua code is the table constructor and even that has an
