I would like to see something in the lines of

function dump(t)
  local seen = {}
  local function recurse(t)
        -- do the work here
        if type(v)=="table" and not seen[v] then
            seen[v] = true
            recurse(v)
        end
  end

Question #1: Correct?
Question #2: Tail Call?
