Then I might as well use init/action/result, as the original poster
did. Also according to him, having it all in DRL is sometimes
preferable. If you have the collection already there (not as the
result of a "from collect" as in my example) a direct transformation
from collection to collection would be preferable.

But, again, I think this is too rarely needed to warrant a new feature.
