This was removed in the lead up to ASDF2 (826b12b0 aka 1.636 from 2010-03-15 by me), for better portability to implementations that didn't support the "long" method combination format (I believe CLISP and ABCL at the time, though they added them since, possibly others).
So we *are* using the regular :around method combination, but in one case, I've split a gf in two: perform became perform and perform-with-restarts. —♯ƒ • François-René ÐVB Rideau •Reflection&Cybernethics• http://fare.tunes.org Down to Gehenna or up to the Throne, He travels the fastest who travels alone. — Rudyard Kipling _______________________________________________ Asdf-devel mailing list Asdf-devel@common-lisp.net http://common-lisp.net/cgi-bin/mailman/listinfo/asdf-devel
