Hello,
I wonder if :s would be sufficient here? I don't have an opinion on which
one is better for this particular transformation (don't change the patch
because of my comment), we just seem to be getting more and more uses of
single_use in match.pd, maybe at some point we need to revisit the meaning
of :s or introduce a stronger :S.
