There are many more methods than just #[]= and #each that should be
(re)defined for an insert-order Hash --- including #delete, #delete_if,
#clear, #keys, #values, and others. The OrderedHash on RAA goes a
long way towards (re)defining the methods that might make sense
for such an object.

Fixing (or overriding) the #== method (depending on the semantics
you desire) would probably be a trivial matter (adding a check
that the second hash is also an OrderedHash seems a likely choice). That
module's author has been quick to respond to bug reports/fixes in the
past.
