Stefan, do we have a way of causing the cl-defmethod dispatch reject a method due to a failed predicate? The relevant method of multisession.el says: (cl-defmethod multisession-backend-value ((_type (eql 'sqlite)) object) How can I modify this (or its callers?) to make this implementation be called only if sqlite-available-p returns non-nil? Btw, it looks like it's okay to have cl-defmethod without a cl-defgeneric for the same method? is that expected?
