 # SortedSet implements a Set that guarantees that it's element are
 # yielded in sorted order (according to the return values of their
 # #<=> methods) when iterating over them.
-# 
+#
 # All elements that are added to a SortedSet must respond to the <=>
 # method for comparison.
-# 
+#
 # Also, all elements must be <em>mutually comparable</em>: <tt>el1 <=>
 # el2</tt> must not return <tt>nil</tt> for any elements <tt>el1</tt>
 # and <tt>el2</tt>, else an ArgumentError will be raised when
 # iterating over the SortedSet.

 # == Example

 #   require "set"
-#   
+#
 #   set = SortedSet.new([2, 1, 5, 6, 4, 5, 3, 3, 3])
 #   ary = []
-#   
+#
 #   set.each do |obj|
 #     ary << obj
 #   end
-#   
+#
 #   p ary # => [1, 2, 3, 4, 5, 6]
-#   
+#
 #   set2 = SortedSet.new([1, 2, "3"])
 #   set2.each { |obj| } # => raises ArgumentError: comparison of Fixnum with String failed
