[Zope] Explicitly avoiding acquisition?

Is there a simple way to explicitly avoid a folder subobject to be acquired? That is to say, I'd like to find a given object in some folder, but not implicitly acquired through a parent folder. I guess I can write a External Method implementing a function that brute-force searches the list returned by objectValues() for the object, but this is potentially "slow", at least compared to a dictionary lookup.
