Hello all,

10 programmers result in 20 solution... That's my suggestion:

	function switch(actual)
	  local found = false
	  local case = function(expected)
	    if expected == actual then
	      found = true
	      return true
	    end
	  end
	  local default = function()
	    return not found
	  end
	  return case, default
	end

Usage:

	for i = 1, 4 do
	  local case, default = switch(i)

	  if case(2) then
	    print("two")
	  end

	  if case(3) then
	    print("three")
	  end

	  if default() then
	    print("default:", i)
	  end
	end


You see, you could do all crazy things with this switch implementation...
