Ruby get_range with :reversed?

I see the Ruby cassandra gem now supports :count for get_range, which
means I can get the first of my slice of records when using OPP, but I
can't get the last without get_range supporting a :reversed => true
option. Does the underlying API support reversing a slice?

Cassandra supports slicing columns within a row in reversed order, but
not iterating rows in reverse.
