[Openmcl-devel] Variadic initializers

I would like to perform the equivalent of the following in CCL:

 dictionaryWithObjectsAndKeys: obj1, @"obj1", obj2, @"obj2", ..., nil];

As you can see, this is a variadic call. The openmcl manual has a
paragraph about a rather heavy syntax for sending variadic messages, but
I was wondering if something more practical exists now. I would have
thought something like:

(make-instance 'ns:ns-mutable-dictionary
  :with-objects-and-keys obj1 #@"obj1" ...) ;; no nil at the end ;-)

Thanks !
