It was thus said that the Great KHMan once stated:
> How many other major languages that avoids having a switch 
> construct are there? Lua puts in a utf8 library but not a switch 
> construct?

  Not built in, but ...

	function switch(var,case)
	  if case[var] then
	x = 4
	switch(x, {
	  one   = function() print "yada"  end,
	  two   = function() print "blah"  end,
	  three = function() print "yahoo" end,
	  [4]   = function() print "this is four" end,

  You still have the overhead of a table lookup, but this is about as close
to a switch statement you can get in Lua without changing the language.
