  local t
  t = 
  {
    'one' = function() stuff() t.two() end,
    'two' = function() otherstuff() end,
    'three' = function() morestuff() end,
    'four'  = function() yetmore() t.five() end,
    'five'  = function() otherthings() end,
  }
  t[switchvar]()

  Notice how one and four "fall thorugh" to the following cases.

  Oooh, I'm having flashbacks to BASIC.  I don't think I ever wrote assembly
code this bad ...
