Hi,
There is a problem in the MOP implementation in abcl 1.2.0: It seems that the parameter list for std-find-method-combination has changed, but the corresponding :initform for :method-combination for standard-generic-function has not been updated to reflect this. I now get an error that std-find-method-combination gets the wrong number of arguments in my test suites.
I don't have a good idea how to work around this problem in Closer to MOP, so I believe I cannot officially declare support for abcl 1.2.0.
Another recommendation: The *features* list currently doesn't provide a way to detect the version of abcl. Most Common Lisp implementation have one convention or the other to encode this information. If I had a workaround for the above problem, detecting the version via *features* would allow me to provide a version of Closer to MOP that works with several versions of abcl. (This may, however, not be as crucial as for the commercial implementations.)
Hi Pascal,
As always, thanks for testing. As of #14529, (make-instance 'standard-generic-function) works again. I believe Mark will release an 1.2.1 soon.
