Suppose I define a class foo
(defclass foo ()

Now, when in the debugger, I am asking for the local variables of frame #3, eg:
3] L
SB-DEBUG::ARG-0  =  (#<BAR {A858559}>)


I would like to inspect this variable to understand the crash landing. How am i suppose to do that, given that I am not using slime at the moment.
Thanks for your help.
