Possible addition: scoped class constants

Hi, First up, I'd like to apologise in advance if I'm mailing the wrong place. I have done my homework before subscribing, and this looks to be the right one, but - one never can tell... Formalities out of the way, I've been a long-time PHP developer and I'm sort of considering dipping my feet into things - one thing in particular that bothers me that I'd like to consider looking at is the inability to scope class constants, i.e: class Foo { protected BAR = 5; } is not possible. This is perhaps not all that major, but considering that scoping for variables and methods is supported and respected, it seems like a rather strange omission. Is this perhaps something that would be looked on positively? If so, I might start trying to look into it in my spare time. (note: advice on where to look, what not to do, etc are all very much welcome). Thanks! Robin Burchell
