>From the docs:

  table.insert (table, [pos,] value)

  Inserts element value at position pos in table, [...]
  This function also updates the size of the table by
  calling table.setn(table, n+1).


  table.getn (table)

  Returns the size of a table, when seen as a list. [...]
  if there was a previous call to table.setn over this table,
  the respective value is returned.
