    CLIM 2.0 Beta on LispWorks 3.2.21 Beta 4 and Allegro 4.2.beta2.0

    If I type the following into the CLIM Lisp Listener:

    (clim:accept '(and number (satisfies oddp)))

    then a previous presentation of 13 highlights, but a previous
    presentation of 12 does not highlight.  This is as it should be.  If,
    however, I use CLIM:EXPRESSION instead of NUMBER:

    (clim:accept '(and clim:expression (satisfies oddp)))

    then both 12 and 13 highlight.  Why doesn't AND correctly apply the
    SATISFIES test for CLIM:EXPRESSION just as it does for NUMBER?

This turns out to be a subtle bug in the EXPRESSION type.  I have a fix
for it, but it slightly changes the behavior of some other stuff.  I
haven't yet decided if the other behavioral change is unimportant.
