This is really strange. As an experiment I just created a dirt-simple source file named "test1.lisp" in an isolated directory.

(require :cl-ppcre)
(use-package :cl-ppcre)
(describe 'cl-ppcre:regex-apropos)

When I compile and run this I get the following:

; compiling file "/home/jcunningham/slime/test1.lisp" (written 30 OCT 2013 12:50:50 PM):

; /home/jcunningham/slime/test1.fasl written
; compilation finished in 0:00:00.002
CL-PPCRE:REGEX-APROPOS
[symbol]

REGEX-APROPOS names a compiled function:
Lambda-list: (REGEX &OPTIONAL PACKAGES &KEY (CASE-INSENSITIVE T))
Derived type: (FUNCTION (T &OPTIONAL T &KEY (:CASE-INSENSITIVE T))
                 (VALUES &OPTIONAL))
Documentation:
    Similar to the standard function APROPOS but returns a list of all
    symbols which match the regular expression REGEX. If CASE-INSENSITIVE
    is true and REGEX isn't already a scanner, a case-insensitive scanner
    is used.
Source file: /home/jcunningham/quest/robom/plotwave.lisp

This is a fresh slime session started in a new emacs. The file it is pointing to is something I haven't been working with for more than a week and most definitely does NOT contain regex-apropos by any package name. But it does contain a defpackage, which looks like this:

(require 'cl-fad)
(require 'cl-extra)
(require 'cl-ppcre)
(require 'quaternion)
(require 'graham))
(defpackage #:cnc-user (:use :cl :quaternion :cl-extra :graham :cl-fad :cl-ppcre))
(in-package :cnc-user)

It would appear that somehow when I last compiled this piece of code it modified something persistently for slime so that it now thinks - from any session I start - that functions in these packages have source code located in this file. The functions are found by SBCL because they do work. It is Slime that is going wrong here.

I see that I was using the 'cl-ppcre designation for the package that you say is not legal Common Lisp. I have no idea how that would affect things. I will change this in the future, but I am at a loss to see how to get back to the behavior Alt-. once had.

I am running SBCL 1.1.11 on this machine, and SLIME 2013-06-26
