> DEFINE-CONDITION Name (Parent-Type*) (Slot-Spec*) Option*
> Define NAME as a condition type. This new type inherits slots and its
> report function from the specified PARENT-TYPEs. A slot spec is a list of:
> (slot-name :reader <rname> :initarg <iname> {Option Value}*
> 
> The DEFINE-CLASS slot options :ALLOCATION, :INITFORM, [slot] :DOCUMENTATION
> and :TYPE and the overall options :DEFAULT-INITARGS and
> [type] :DOCUMENTATION are also allowed.
> 
> The :REPORT option is peculiar to DEFINE-CONDITION. Its argument is either
> a string or a two-argument lambda or function name. If a function, the
> function is called with the condition and stream to report the condition.
> If a string, the string is printed.
> 
> Condition types are classes, but (as allowed by ANSI and not as described in
> CLtL2) are neither STANDARD-OBJECTs nor STRUCTURE-OBJECTs. WITH-SLOTS and
> SLOT-VALUE may not be used on condition objects.
