[lift-devel] Slime warnings

[Gary King]

I haven't pushed the changes yet, but I think I have a fix that works  
in SBCL 1.0.20 (and fails to work in SBCL 1.0.12). It involves using

that I've stolen from metatilities-base. The earlier versions of SBCL  
don't seem to respect the declaration. I'm looking into this.
