Re: switch statement

[lhf@... (Luiz Henrique de Figueiredo)]

Here is a nicer implementation:

 function switch(t)
  t.case=function (self,x)
		 local f=self[x] or self.default
		 if f then
			 if type(f)=="function" then
				 f(x,self)
			 else
				 error("case "..tostring(x).." not a function")
			 end
		 end
  end
  return t
 end

  a=switch{
  [1]=function (x) print(x,10) end,
  [2]=function (x) print(x,20) end,
  default=function (x) print(x,0) end,
  }

 a:case(2)
 a:case(9)
