It's arguably more user-friendly, too, although part of me feels like
it would be better to try to preserve the topological ordering in some
way.  If something cascades to foo and from there to bar and from
there to baz to and from there to quux, emitting the messages as

drop cascades to bar
drop cascades to baz
drop cascades to foo
drop cascades to quux

is arguably not going to be too helpful to the user in understanding
the chain of events, however nice it may be for regression testing
