Not really because if you want a container shared across the methods it wouldn't be very feasible. I'm sure there are some hacks you can do but I just think it'd be a pretty common use case. Stefan, you have done a lot of research in this area and I assume have also looked at the most common use-cases where this functionality is used in other languages. What is your sense? > again i prefer to keep the feature as simple as possible without > crippeling it the point of not being useful. This suggestion is actually geared towards the opposite of crippling (private property is actually an addition). I actually think this is something which would be a very common use case for our users. Btw, the 2nd part where I recommend brainstorming about a slightly stronger contract would actually also drive more towards simplicity. In any case, I think we all agree this is a good thing to have in PHP. I am not advocating the opposite but I would like to explore some of these use-cases and options for a slightly stricter contact. Andi
