Re: format for description of generic functions in chapter 2

[Masinter.pa@Xerox.COM]

"To me lambda-list congruence seems equally applicable
to all generic functions and methods, and furthermore it's hard to see
how
generic functions could work or users could call them if there wasn't
lambda-list congruence.  . . ."

There were numerous discussions of alternate rules for lambda-list
congruence than the ones that made it into the spec. Generic functions
could implicitly assume that they were defined with &rest, for example,
yet allow some methods to have &REST and others &KEY or even a set of
&OPTIONAL arguments. Allowing the number of arguments to vary by class
seems possible, too, although it might require a run-time test at method
entry to determine if the generic function handed on too many arguments
for that particular method.
