Hey all,
As currently implemented:
(defn foo
[& {:keys [x y z] :or {x "x-default" y "y-default"} *:as* args}]
args)
(foo) => *nil*
Is there a way anyone can think of (macro, etc.) that'd allow for something
like this:
(defn foo
[& {:keys [x y z] :or {x "x-default" y "y-default"} *:merge-as* args}]
args)
(foo) =>* {:x "x-default" :y "y-default**}*
I.e. to merge the :or defaults over the :args binding?
Rationale: one of the nice things of setting defaults via :or is that
they're visible to callers via :arglists. This'd help make the process more
convenient in the (relatively common) case where you'd like to preserve
arbitrary args, but apply some defaults in a transparent way.
Thanks!
