Hi,

This worked for me:

irb(main):023:0> class NString < String
irb(main):024:1>  def gsub!(*args, &blk)
irb(main):025:2>  super(*args, &blk)
irb(main):026:2> end
irb(main):027:1> end
=> nil
irb(main):028:0> s = NString.new("hi")
=> "hi"
irb(main):029:0>  s.gsub!(/(hi)/){$1}
=> "hi"

Hope this helps,

Jesus.
