Almost seems like Zend_Registry is being designed using a mailing list thread. I thought there was supposed to be a proposal process followed by a review process then some incubator code and testing. Oops. Wait a second. we did have a proposal. It was reviewed and approved. And code was checked into the incubator. But then some deleted it. Very sad.
In any event, the attached files match roughly 99% of what has been discussed on this thread. Maybe they will save someone some typing.
