This is a new step in my quest (or curse) to provide properties to Java.
I've written a new version of the proposal (the third draft) of the property spec, available as a google doc
property draft (v3)

During the last month, i've written a new prototype from scratch that follows the specification. The prototype is not available yet, mostly because i change the spec too frequently, but i hope to post a blog about its availability in one or two weeks.

If you are concerned by the implementation details of the prototype, i will soon post messages that describe its implementation to Kitchen Sink Language mailing list.

I wait your comment about the spec.

Cheers,
Rémi
