I'm concerned about performance. Grep performance is relevant to some. Now, while I don't care if this grep is slower than what we are using right now, I do care if it's _complexity_ is greater. So, please, could you make sure the algorithmic complexity is not greater, either by benchmark comparision, or by examining the code? I would do it, if I had time. But right now I don't, and there is no need to keep this waiting. -- Daniel C.
