Really hope this is the last update tonight.

The repl's package matters because my source file didn't have a proper 
in-package form.  Thus slime doesn't see the actual class, and the pause 
doesn't occur.

So my current workaround is to put (in-package :cl) before a form 
containing make-instance, edit it, then remove the in-package kludge.
