`sod-class'. All of the arguments are then passed to `make-instance';
further behaviour is left to the standard CLOS instance construction
protocol; for example, `sod-class' defines an `:after'-method on
- SHARED-INITIALIZE.
+ `shared-initialize'.
Minimal sanity checking is done during class construction; most of it is
- left for FINALIZE-SOD-CLASS to do (via CHECK-SOD-CLASS).
+ left for `finalize-sod-class' to do (via `check-sod-class').
Unused properties in PSET are diagnosed as errors."
