The behavior is as documented, though I'm not sure I'd call it "intended",
exactly.  :)  You can fix this with either a seperate statement, as you've
noticed, OR by placing the __roles__ computation *first* in the WITH SELF
statement.  This will ensure that it is already computed before the other
items execute.
