Metaobject classes are chosen in a fairly standard way.
\begin{itemize}
\item All metaobject definitions support a symbol-valued property, usually
- named @|@<thing>_class| (e.g., @|slot_class|, @|method_class|), which sets
+ named @|@<thing>{}_class| (e.g., @|slot_class|, @|method_class|), which sets
the metaobject class explicitly. (The class for a class metaobject is
taken from the @|lisp_class| property, because @|class_class| seems less
meaningful.)
