[Zope3-Users] Seeking Explicit Acquisition Support re Climbing Containment Hierarchy

[Jeff Rush]

I know that Zope3 dropped 'implicit' acquisition, but is there any support for 
*explicit* acquisition that walks the __parent__ containment hierarchy. 
Something that follows the same rules as traverse() to look up a name, but 
from bottom-to-top instead of traverse() from top-to-bottom?

I know I can roll my own and special case it but I thought I'd ask before I 
duplicate existing functionality.
