The following steps should show the "problem" I'm having:
1. Create a file, foo.clj, containing
(ns foo)
(def qux 5)
(defn bar [x]
(* x qux))
2. Start Slime.
3. Back in foo.clj, C-c C-k to compile and load the file into slime.
4. In the slime-repl I can see that foo/bar is defined:
; SLIME 2009-07-06
user> foo/bar
#<foo$bar__1293 foo$bar__1...@442fb9e4>
5. I can set the foo namespace from the repl by typing ",i foo":
user>
foo> (bar 5)
25
6. Now switch back to foo.clj and change the definition of bar in some
uninteresting way, e.g.,
(defn bar [x]
(* x x qux))
7. Now evaluate that definition, C-c C-c
8. Fail: you get an error
Unable to resolve symbol: qux in this context
[Thrown class java.lang.Exception]

Note that the repl was set to the namespace containing qux! Indeed, if
you abort the evaluation:
foo> qux
5
It seems that the environment the per-definition compilation takes
place in doesn't match that of the underlying repl, or something. I
don't know. I'm just confused by it.
Does this make more sense now?
