Gah! I'm an idiot, Sorry! Here:

function enum(strEnumSetName, tblEnumList)
   typecheck(strEnumSetName, "string")
   typecheck(tblEnumList, "table")
   return function()
       for k, v in ipairs(tblEnumList) do
          HackEnumCntr = HackEnumCntr + 1
         _G[k] = 2^HackEnumCntr -- Figure something for handling over 
overflows?
          -- Is it even a possible concern? Never was in my experience...
       end
   end
end
