[Hans Hübner]

Patrick,

you cannot specialize a generic function on the run-time value of a
variable.  In your method definition, you are trying to specialize the
ACCEPTOR argument on (EQL *TEST-ACCEPTOR*)), but *TEST-ACCEPTOR* in that
definition will be evaluated at compile-time, not at run-time.  Thus,
you're probably specializing on NIL or some other random object.  Is there
any reason why you want to specialize on a particular instance rather than
the class of the acceptor (or T)?
