[Ecls-list] ContextL functions with &key args don't work properly in ECL.

[Alexander Gavrilov]

Hi,

Using the following definition:

(define-layered-function foo (a &key)
  (:method (a &key)
    (print a))
  (:method ((a number) &key b)
    (call-next-layered-method)
    (print b)))

in the following way doesn't work:

(foo 5 :b 5)

because the base method complains about an unknown key.

This is incorrect because a key is valid if any of the applicable
methods accepts it. Moreover, it breaks even if &allow-other-keys
is added to the generic function parameter list (but not to the
methods). The standard defmethod implementation in ECL
supports this by adding &allow-other-keys to the method
function lambdas, but CloserMOP doesn't do it.

Also, even with (debug 3) layered method calls appear in the
stack trace as useless uninterned symbols.
