Sorry, David, but I disagree.  It may not be buggy (as the bugginess is
properly documented :), but it is certainly incorrect.  Re-read my
post.
Hash.reject, which is also an Enumerable, DOES return a hash.
Hash.find_all which is algorithmically the same as Hash.reject but
without a negation, does not.
Someone forgot to override find_all in the Hash case, but did remember
to do it for Hash.reject.  Or, if you are of the belief that indeed
Enumerables should always return an array, Hash.reject was incorrectly
overridden when it shouldn't have been.
