[slime-devel] Package handling

[Nikodemus Siivola]

If I edit a file like the following:

   (defpackage :foo
     (:use :cl))

   (in-package :foo)

   ...more core...

before the DEFPACKAGE has been evaluated, symbol completion
doesn't work in the file -- nor does much anything.

I can't even C-c C-c the DEFPACKAGE, because that part of the
file is taken to be in FOO as well.

So, two suggestions:

  * If there is an IN-PACKAGE form, assume the part of the
    file above it is in CL-USER.

  * If there is an IN-PACKAGE form, but the package doesn't exist,
    assume the whole file is in CL-USER.

Cheers,
