Re: petition to keep ipairs alive

[Fabio Mascarenhas <mascarenhas@...>]

Apart from convenience, the new ipairs also uses an __ipairs
metamethod where available, making the "for i, v in ipairs(c)" idiom
useful for iterating on user-defined sequences, not just regular Lua
lists. It would feel strange to use pairs to iterate on sequences.
