    You're right, it looks encouraging. To make sure I have it right,
    could you tell me what you get on this lattice for E1?

    (defclass c1 (top) ())
    (defclass c2 (top) ())
    (defclass c3 (top) ())
    (defclass d1 (c1 c2) ())
    (defclass d2 (c1 c3) ())
    (defclass e1 (d1 d2) ())

I assume I'm supposed to add (defclass top () ()).
I get e1 d1 d2 c1 c3 c2 top (from running code, not hand execution).

    My reading of your algorithm says that we start:

    e1 d1 d2 c1

    At this point either c2 or c3 could come next. Scanning right to
    left, d2 comes first, and so c3 is next, then c2. The final order
    is:

    e1 d1 d2 c1 c3 c2 top

    I might be misreading your algorithm, so I'm simply asking for 
    confirmation. It's hard to know what is most intuitive in this case.

You got it right.  This is one of those cases where it's impossible to keep
the superclasses of d1 together, so anything is going to be ugly.

    Also, if you could send some more examples, I'm trying to get a superfast
    algorithm to do the CPL computation. 

I've been drawing examples directly from Flavors, and Flavors is more general
than CLOS, since it allows the local precedence order of a class to be specified
as a partial order rather than a total order, so it's a little difficult.

For simple examples, here are the ones I typed in to my file.  Change defflavor
to defclass in the obvious way.  I'm sending you more or less raw crappy text
from my file, I hope you can decode what you need from it.

;This is supposed to demonstrate that Gabriel-3 / Bobrow don't work even in the

(DEFCLASS E ())
(DEFCLASS F ())
(DEFCLASS X ())

;Flavors, Gabriel, Bobrow produce A B C D E F X Y
;Gabriel-3 produces A B C D E F Y X
;Gabriel-4A produces A B C D E F X Y
;Frankly I'm not sure it matters which one you do...


Here are some real examples.  The first argument to TEST is the
collected precedence relations, an alist of elements (foo bar1 bar2 bar3...)
where the bars are classes that must precede foo, and the order of the
bars doesn't matter.  The second argument to TEST is the direct superclass
relations, an alist of elements (sub sup1 sup2 sup3...), where the sups
are the direct superclasses of the subs in most-specific-first order.
The third argument to TEST is the class precedence list expected.
I'm not sure if I got "all possible cases" into the real examples,
I just collected a few flavors that I had noted as interesting before.
Some of these may have been interesting just to make the Bobrow-Kiczales
algorithm get very slow (before I fixed it).
