I'm converting an application using New Flavors to use PCL on a
Symbolics 3650 (7.2). I have several cases where the code uses a flavor
instance variable as an argument to SCL:LOCF. The resulting locative is
then used with SCL:PROCESS-LOCK and SCL:PROCESS-UNLOCK.
I can't seem to get the same functionality with class slots.
Would anyone care to make suggestions about how to proceed? Is there a
way to get a locative to a PCL class slot?
I have made additions to VD PCL that provides LOCF and LETF support.
I have not had a chance to add this to MayDay! Mayday! PCL. The basic
idea is to extend the walker to handle LETF, and define optimizers for
slot-location. It is a bit tricky because of how with-slots works,
but it shouldn't be much different than before. I can send you what i
have if you like.
