This sounds like one of those variable names with a type prefixed to
it, like sequence_string, or sequence_array. They look ugly. It would
have mad more sense if Ruby were ever to ship with two different Hash
implementations. Besides, the aliasing can be done at the application
level too. So if the Hash implementation changes tomorrow, you are
free to re-alias to some other ordered hash implementation.
