That's because "me" is a function, which works directly from the
object architecture and "the owner of me" is a property expression
which must necessarily be evaluated, during which any information
about the object architecture is lost.

It's actually a "feature": this is the way HyperCard does it, and so
is the way we implemented it. Of course, you can't have multiple
groups/backgrounds on a card in HyperCard, so the ambiguity problem
doesn't come up.

Agreed. Any objection to changing behavior of "the owner" property so
that it returns the long id of the object instead of the name? Seems
to me that this will eliminate the ambiguity problem with minimal
backward compatibility problems...
