But I am not expecting any miracles here. GNU grep does pretty much everything it can to achieve performance -- including eschewing the standard library buffering system as I am doing. I can probably match the performance at some point, but I doubt it's worth worrying about.
I wonder if there's realistic real-world cases where you could beat it due to being a library solution and skipping the cost of launching grep as a new process. Granted, outside of Windows, process launching is considered to be fairly cheap, but it still isn't no-cost.
That would still be a nice feather in D's cap: Comparable to grep for large data, faster than spawning a grep process for smaller data.
