[SOLVED] Emacs-Haskell-Mode Garbage on First Load

Question

I installed emacs-haskell-mode from pacman and I have this in my .emacs file:
(load-library "haskell-site-file")
haskell-site-file.el autoloads haskell-mode when I open a haskell file.  All works fine, but the very first time I open a haskell file (and load haskell-mode), this garbage gets spit out in my minibuffer:
#[nil "\300C\207"
[t]
2]
I've only been on emacs for a couple of months now and I've never seen that output before.  Haskell mode works fine as far as I can tell once it's loaded so the garbage output isn't causing any problems, but I'm just curious as to what it is and why it's there.

Answer 1

If you're new to emacs, I don't expect you'd understand much lisp yet, but here is the answer:
When including haskell-mode the following is run.
(eval-when-compile
;; Emacs 21 defines `values' as a (run-time) alias for list.
;; Don't maerge this with the pervious clause.
(if (string-match "values"
(pp (byte-compile (lambda () (values t)))))
(defsubst values (&rest values)
values)))
See the line starting with 'pp'.   That basically says to pretty-print the value of the byte-compile.  It pretty prints to the echo area (what you refer to as the minibuffer).  If you eval the byte-compile you get the same value you're seeing.
This is a very long way to say that it's probably a bug.
