Re: String Extension Proposal

Jessie, I can see how this will be useful. Two things make me hesitant about putting this in PECL right now: - String is such a generic name for a non-core class - The PHP core has a big patch for Unicode support pending (we're waiting to release 5.1 before merging it). I think there might be some merit to having some kind of String class in the core; IIRC Derick was talking about something like that with full unicode support. Let's see what the other core guys think about this before making a decision on having it in PECL. --Wez.
