Ah, ok.  I confess that when working with maxima, I use neither slime 
nor imaxima or emaxima or whatever they're called.  I just basically 
reload the whole file that I'm editing.  That's not so nice compared to 
slime.

And the little bit of code I posted earlier to allow slime to talk to 
maxima doesn't work so well, at least with the version of slime I have. 
  I should try to update that so that it works.  I should also learn how 
to use emaxima or imaxima, or whatever they're called.

If both of those are working, you should get a nice slime environment 
for hacking on the Lisp parts, and a nice maxima environment for working 
with maxima code.
