18:03:49easyeFiled <https://abcl.org/trac/ticket/485> for the problems with cl:eval of non-congruent generic method signatures
18:04:02jackdanieleasye: the congruency between the gf and the method is defined (among other rules), that method must have all key arguments from the generic function
18:04:45jackdanielwhen you implicitly define the generic function via defmethod, and defmethod has &key arguments, the generic function is defined as (defgeneric foo (a &key)) [i.e for (defmethod foo ((a integer) &key z d))
