Well, if C++ had no operator++ it would be easy enough to write:
    template <class T> T preincrement(T& value)
    {
       value = value + 1;
       return value;
    }

You could write a generic function in Ada, except that it couldn't
return a value, and you would have to instantiate it for every type
you wanted to increment.
