=begin
 Array is corrupted if you break out of a delete_if { ... } loop. I would expect that the elements already marked as deleted would be deleted, and the remainder of the array would be unchanged.
 
 >> a = [5,6,7,8,9,10]
 => [5, 6, 7, 8, 9, 10]
 >> a.delete_if { |x| break if x > 8; x < 7 }
 => nil
 >> a
 => [7, 8, 7, 8, 9, 10]
 
 >> RUBY_VERSION
 => "1.8.7"
 >> RUBY_PATCHLEVEL
 => 174
