Maybe we should be over on the PhyloCode list by this stage, but if
the new version of the Code really does mean to say things like "you
should have EuWHATEVER if there's no WHATEVER", then it has introduced
all that is worst about rank-based nomenclature and needs to be put
out of its misery. When changes in one taxon cause changes in
another, something is badly wrong.
