method-combination
objects do not contain the arguments, merely the type. There is a single
method-combination
object per type.
Therefore the value returned by
generic-function-method-combination
, and the default value of the
:method-combination
initarg, and the
:method-combination
argument processed by
ensure-generic-function-using-class
are specific only to the type of the method combination.
Also,
find-method-combination
is not implemented.
