Building your own PHP parser is _very_ hard and is PhD (Paul Biggar:) level stuff if you wan't to get all the edge cases right. Having _the_ official EBNF would make this easier. I know there is a lot of historical reasons for this and that creating and maintaing said EBNF is a very serious task, one that is maybe too big for a non-paying open source project. But still I have to ask if I'm the only one thinking about this or is there something I'm being completely ignorant about? Happy newyear! Rune Kaagaard
