yes, thank you, that is what I was referring to + the :or and :as like:
(defn somefn
[req1 req2 ;required params
& {
:keys [a b c d e] ;optional params
:or {a 1 ;optional params with preset default values other than the
nil default
; b takes nil if not specified on call
c 3 ; c is 3 when not specified on call
d 0 ; d is 0 --//--
; e takes nil if not specified on call
}
:as mapOfParamsSpecifiedOnCall
}]
(println req1 req2 mapOfParamsSpecifiedOnCall a b c d e)
)
;=> (somefn 9 10 :b 2 :d 4)
;9 10 {:b 2, :d 4} 1 2 3 4 nil
;nil
this may be good for most people, but not for me. I've tried implementing
something for me but I have it only half way done (and I haven't looked at
in in a few months) it's here [1] but u won't like how it looks xD
meanwhile I realized what OP was saying with destructuring the arg vector.
