Subtract has to be defined for the private type's parent (as a renaming of "-"), so the private type also has Subtract defined. Then you can define "-" for the private type as a renaming of Subtract. Here, "-" refers to the explicitly defined operation, which is a renaming of Subtract, so this is infinite recursion. -- Jeff Carter "There's no messiah here.
