That section (in 4th ed, pp 638) does not explain sibling predicates of
which more than one is a numeric predicate, and in the section on
patterns, that is neither mentioned. I agree it is explained in more
general terms, but I tried to find a source for those cases I laid out
in the original post, and couldn't readily find one (that doesn't mean
there is none, of course).
