23:35:08monashin first report above, i wanted to define s-v-u-c for a virtual slot so slot-value works for a slot which is not found in class-slots, i guess that's not possible in ccl
23:35:43monashbecause slot-value checks for the slot in class-slots before calling s-v-u-c
0:09:12rebmonash: Try the code here https://codeberg.org/pcostanza/mop-features and see what it says about what CCL implements.
5:02:19monashs-v-u-c will just not work if the first argument is specialized on standard-class ?
