Niitsuma,
You might like to look at share/contrib/multiadditive.lisp. Maybe you could figure out
how to declare a function to be outative (say multioutative) in each of its arguments.
Then declare(k,multiadditive), declare(k, multioutative) might automatically do what you want
without the call to ev(..., nouns).
