True, but I doubt many people will use properties called for example:


Or some silly name space like that.

My problem with the real local properties is that I think they will
a lot of work and thought before we can have something really rubust.
If, as we have done in the past, put out there something that we have
really considered all the concequences properly, we will finish with
all sorts of backward compatibility issues when we find the drawbacks
(or the users find them). It would not be the first time this happens
so I am talking based on the historical experience.

The payoff of general local properties seems quite limited, as far as I
can see.
Have you found any compelling usage for them on their own?
<ant> & co. already provide stack (but is expensive).

Whatever we do in this regard, we probably need to provide for
references also.

But he, I just though about this for 30secs before proposing it,
so shoot at it if you think is not worth the electrons is written on :-)
