In our case, perhaps it needs to be::

which causes a walk up the containment hierarchy, searching for objects of the given meta_type.

I would suggest that it ask for an interface, rather than a meta_type. Otherwise, you've hardwired yourself into a single object type with no extensibility. For example, an SQL method wants the nearest SQL connection, but shouldn't have to explicitly ask for each kind of SQL connection (Sybase, Oracle, etc.)
