Lua is very flexible and very fun to hack! With a different approach [0], you can get a switch on tag that feels more like a "standard" switch statement, eg.:

  result = switch(shape) {  
    rectangle = function(r)  
      return "a rectangle with width " .. r.width  
    end,  
    function(s)  
      return "an unknown shape"  
    end  
  }

Can't easily get rid of the pesky functions, though.
