[Zope-dev] Move implementation of getParent to zope.location?

There are two functions in zope.traversing.api, getParent and getParents, that are rather closely related. The former is implemented right in that module while the latter adapts its argument to zope.location.interfaces.ILocationInfo and calls getParents() on that. Why is getParent not a part of ILocationInfo? If there's no good reason, I'd propose adding getParent() to the interface and changing the getParent function in zope.traversing to work similarly to getParents, i.e. call a method on an ILocationInfo adapter. -- Thomas
