If we're going to do this, I'd like to do it now before the new regex modifiers go in. Aristotle withdrew his opposition and became a supporter after he understood what the proposal really was. Sorry for being unclear. If there's no opposition, we need to settle on what is the syntax is. Ben originally proposed (?~ I thought (?. was better because the tilde can be too easily confused with a hyphen, (?- which is also legal right after the question mark. Another option is to make it a two character sequence, the first one is a tilde, say, and I'm not sure what the second one should be. This would allow future expansion so that some other 2nd char could mean something else. Mostly people wouldn't type this, it would be inserted by the regex compiler.Thread Next
