In short, to say that :immediate is unpredictable is to make a null statement, because in practice, all computation is unpredictable.
Yes. And it is the designer's choice to introduce unpredictability intothe PIR level. If the designer allows rand() inside :immediate, it's the designer's call; if the designer allows rm -rf, it's again the designer's
call. There are degrees of unpredictability, and currently there is no evidence that we require any of it in hand-written PIR code.You ruled that we wait to see if a use case come up; that is fine with me.
And hey, even if we reach consensus, there is no security model yet toimplement any of this on, so I prefer to have this discussion when Parrot
can actually tell rm-rf apart from rand(). Thanks, Audrey
