Acquisition wrappers *look* a lot like the base object. But, as you
mentioned in your original message, they're of different types. repr on the
wrapper may look like the base object, but it searches that object and all
the way up the chain to find the attributes you're looking for.

The root object is an Application... I'm not sure what that Folder is that
you're encountering...
