Is deprecating ipairs really necessary? I know it can be replaced for
most parts with a numeric for loop, but these often look and feel
clumsy. There are a few other "syntactic sugar" constructs in Lua, so
why is ipairs singled out?
It's trivial to add yourself, as demonstated in PIL:
function iter (a, i)
i = i + 1
local v = a[i]
if v then
return i, v
end
end
function ipairs (a)
return iter, a, 0
end
