I was having issues making it work properly... but I finally managed to 
do it (stateless)

local findpairs
do
  local function _findnext(stringandpattern, index)
    -- only branch if index = 0
    if index > 0 then
      -- this should always give a match,
      -- as we're starting from the same index as the returned match
      local x,y = string.find(stringandpattern[1], stringandpattern[2], 
index)
      return string.find(stringandpattern[1], stringandpattern[2], y+1)
    else
      return string.find(stringandpattern[1], stringandpattern[2], 
index + 1)
    end
  end
  function findpairs(string, pattern)
    return _findnext, {string, pattern}, 0
  end
end
