Does update-dependent call update-dependent on its dependents,
or is the dependent structure flat? This probably needs to be
The intent was that update-dependent would flat. Of course, if the way a
particlar method on update-dependent works is to call reinitinaize-instance then
Why does finalize-inheritance have to do its work by calling
(UPDATE-DEPENDENT class class)? It seems backward to me. Why can't
UPDATE-DEPENDENT call (FINALIZE-INHERITANCE dependent), and
FINALIZE-INHERITANCE do the slot and CPL computation?
Because finalize-inheritance is defined to do nothing after the first time that
inheritance is finalized. This is to avoid having redundant calls to
finalize-inheritance recompute each time.
I understand that, but why does finalize-inheritance have to be called
redundantly? the code that calls it can check the status of the class
before. This seems cleaner.
