I haven't made a thorough comparison, but it seems that the new
dispatch code is significantly faster. Here's the little test I used:
(defclass sm-class0 () ())
(defclass sm-class1 () ())
(defmethod sm-fib ((x sm-class0)) 0)
(defmethod sm-fib ((x sm-class1)) 1)
(defmethod sm-fib (x)
(cond ((eq x 0) (sm-fib (sm-class0 "toto")))
((eq x 1) (sm-fib (sm-class1 "toto")))
(t (+ (sm-fib (- x 1)) (sm-fib (- x 2))))))
I byte-compiled it with emacs-24, and then ran the .elc with both
emacs-24 and master: for (sm-fib 23), the emacs-24 code took about twice
as much time to complete.

It "should" work without recompiling anything. So please, before
recompiling, try to keep the problem around to see if we can fix it.

Ah, that makes sense.

Aha!

Ah, nice, indeed (tho I wouldn't put a quote in front of symbols since
that confuses the difference between the value and an expression which
returns this value).

Its interactive spec should probably use read--expression (which clearly
needs to be renamed to something without "--") so as to get completion.
