Subject: Which gem has a class like 'sorted list'?

For example:

sl = SortedList.new {|x| -x }
 # the block is sth just like for sort_by method

sl << 2 << 6 << 10 << 3 << 8
 # each time inserting an elem into the list,
 # the elem will be put at the proper position

sl # will be [10, 8, 6, 3, 2]

Is there any gem has such class? Maybe there's no need to invent the
wheels?
