clos: method combinations: obsolete comment
In src/clos/combin.lsp we have invalid comment about a nature of the method combination
- 47fdf3ee is a hash of commit in 2003 which introduced the comment
- 6e58b9c4 is a hash of commit in 2012 which invalidated the comment
;; ----------------------------------------------------------------------
;; DEFINE-METHOD-COMBINATION
;;
;; METHOD-COMBINATION objects are just a list
;; (name arg*)
;; where NAME is the name of the method combination type defined with
;; DEFINE-METHOD-COMBINATION, and ARG* is zero or more arguments.
;;
;; For each method combination type there is an associated function,
;; and the list of all known method combination types is kept in
;; *METHOD-COMBINATIONS* in the form of property list:
;; (mc-type-name1 function1 mc-type-name2 function2 ....)
;;
;; FUNCTIONn is the function associated to a method combination. It
;; is of type (FUNCTION (generic-function method-list) FUNCTION),
;; and it outputs an anonymous function which is the effective method.
;;
I'd like it to be resolved by explaining how things work now (instead of simply removing the invalid comment). This ticket has low priority to me.
