Suppose I type the following at a *slime-repl<n>* buffer: ; CMU Common Lisp Port: (localhost 32816) Pid: 805 CL-USER> (defclass myclass () ((slot :initarg :slot :accessor slot))) #<STANDARD-CLASS MYCLASS {485E7535}> CL-USER> (slot If I place the cursor just after "(slot" and press space, I get the following SLIME error: :NO-LAMBDA-LIST fell through ETYPECASE expression. Wanted one of (NULL CONS STRING). [Condition of type CONDITIONS::CASE-FAILURE] Restarts: 0: [ABORT] Return to SLIME toplevel. 1: [ABORT] Return to Top-Level.
