I did, but Edebug cannot step into cl-defmethod's, cl-defgeneric etc.
Any tricks up your sleeves to make that work?  I'd give half the
kingdom for being able to debug into those.

Thanks, that was what I needed.

I fixed the problem.  I cannot believe we still have (had) such code
in our repository, but facts are stubborn.

So, one less bug that's blocking v25.1 ;-)
