I'm already at the point where I always use next,tbl and never
pairs(tbl). It will be only a small step from there to always using
inext,tbl and never ipairs,tbl:

function inext(tbl,k)
   k=(k or 0)+1
   local v=tbl[k]
   if v then return k,v end
end

It would be nice if standard Lua offered this inext built-in, but the
beauty of Lua is that all of the standard library is easily customizable.
