I'll discuss this on the Zope 3 list, but not on the ZPT list.

For here, it is sufficient to say that for Zope 3 we want to control 
through policy whether something is implicitly called or not.

The problem is not that you can explicitly not call using 'nocall:', but 
that the component is always called if it has a '__call__' method.
