This is possible using "-do" (distribute outputs) in which case inlet~s
are passed in unchanged.

OTOH, there's no good way to make a clone~ object in which some inlet~s
are distributed and others are passed unchanged, or similarly with
outlet~s....

Incidentally, now I think the word "distribute" is ambiguous - does anyone
have a better word for packing/unpacking on way in and out of clones?
