Silly me -- I need to add a guard against non-integer
elements in the 'item' list.  E.g.:

     def __contains__(self, item):
         if type(item) != type([]): return 0
         if len(item)!=len(self.dice): return 0
         for i in range(len(item)):
             if item[i] != int(item[i]): return 0
             if item[i]<=0 or item[i]>self.dice[-i-1]:
                 return 0
         return 1
