Ah, you're using /g... Yes. Sorry about failing to mention that. It was late and I was tired {excuse, excuse, excuse...} in that case I'd just.. That is essentially what I doing (except with index) in Re: Store larg hashes more efficiently (10e6 md5s in 260MB at 4µs per lookup), because I couldn't work out how to get a regex to do it for me. Hence the question. I'd rather push the check inside the regex engine if I could; and it seems like it should be a reasonable ask; but it has me totally stumped. Even johngg's solution is flawed. :( With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'

In the absence of evidence, opinion is indistinguishable from prejudice.
