That was a typo - all of them are (in-package :ftis-v43), I just 
checked. Currently, if I start a fresh sbcl under slime the only 
functions I can navigate to with Alt-. are system functions (format, for 
example). Any packages I am loading via quicklisp or of my own result in:

Error: end of file on #<SB-IMPL::STRING-INPUT-STREAM {10070EBBB3}>

When I load packages creates and/or loads a fasl under 
~/.cache/common-lisp/<sbcl version>/.. I would have thought that would 
be how it would navigate, but in my case not.

I can open any source file, compile a LOCAL fasl with C-c k and then 
those functions can be navigated into. It used to work on anything. And 
I haven't changed my .sbclrc in years (except to add the suggestion 
yesterday). Here it is:


;; -*-Lisp-*-
(require 'asdf)
(proclaim '(optimize (debug 2)))

;;; The following lines added by ql:add-to-init-file:
#-quicklisp
(let ((quicklisp-init (merge-pathnames "quicklisp/setup.lisp"
                                        (user-homedir-pathname))))
   (when (probe-file quicklisp-init)
     (load quicklisp-init)))

;;; If a fasl was stale, try to recompile and load (once).
(defmethod asdf:perform :around ((o asdf:load-op)
                  (c asdf:cl-source-file))
   (handler-case (call-next-method o c)
     ;; If a fasl was stale, try to recompile and load (once).
     (sb-ext:invalid-fasl ()
       (asdf:perform (make-instance 'asdf:compile-op) c)
       (call-next-method))))
