Thanks Fernando. I'm not an emacs user except when I'm forced to (only 
usable Isabelle/HOL theorem prover interface), but looking at sawfish.el 
indicates that the C-x C-e magic you're talking about invokes 
sawfish-client with the -e parameter. If I replicate that, I can get an 
error back too:

[~]# sawfish-client -e "(3.3)"
*** Remote sawfish error: (invalid-function 3.3)

Also, the in-one-go mode "--" works too:
[~]# sawfish-client --
(3.3)
^D
*** Remote sawfish error: (invalid-function 3.3)

The interactive mode of sawfish-client appears broken though; it does 
something weird and the error goes off into .xsession-errors or 
disappears entirely. I'm not experienced enough to tell what exactly is 
going on in there with all the repl-iterate business.

I guess this will do for now, emacs or no emacs, but a usable repl would 
be nice, as not everyone is an emacs user.

Sincerely,

Rafal Kolanski.
