I don't really know, I haven't tested for it. But even if it is stable in
this version it could perhaps change in later versions and because the help
for Unique does not suggest otherwise, I figure a bit of defensive
programming is warranted.
My habit is to think: "if I need it like that - then I should ensure it is
like that".

Brett.
