    No, there should be just one environment argument.  Perhaps there should be

    demonstrated first.  For the metaclass writer, the point is to be
    consistent about passing the received environment on to FIND-CLASS,

My idea was that the predicate would be the extra argument.  User code
would still be required to pass the argument on to the other functions
(find-class etc.).  User code would pass the value of the :environment
argument, no other values.  The other argument would just be a flag to
user code that this was in the compile environment and things might be
