I'm using SLIME 2.0 so these may already be fixed, but maybe not. The Lisp is CLISP 2.41.

1. The syntax for complex numbers (like that: #C(1 1)) seems to mess with the feature that displays function arguments in minibuffer. It thinks that #C and (1 1) are actually two different arguments, which is annoying.

2. I wrote a function:

(defun fast-orient (start end point) (declare (optimize (speed 3) (safety 0))) (declare (number start end point)) (> (anti-product (- point start) (- end start)) 0))

When I C-c C-c it, SLIME displays the following error:

"FORMAT: The control-string must be a string, not WARN"

[Condition of type SIMPLE-TYPE-ERROR]

Restarts: 0: [ABORT] Abort SLIME compilation. 1: [ABORT-REQUEST] Abort handling SLIME request.

and so on...

3. The indentation of loop macro is strange and annoying. I can never figure out the principle behind it. Maybe some Python-style indentation mechanism could be used?
