This is what I ended up with:
NB. reset random seed if state incremented less than 3 times since
session startup
...
if. +./(1{::9!:44'')=624,>:i.3 do.
9!:1 (_2) 3!:4 , guids 1 end.
s=. createSalt ''
...
My thinking is that if I'm using createSalt in a continuous session,
then I don't really want to be resetting the random seed each time.
I suppose the question now becomes whether it's better, in this case, to
forget about Roll altogether & just to use:
{.(_2) 3!:4 , guids 1
to generate my 4 byte integer salt?
Whatever the answer, I can see that setting the random seed this way
will come in handy for simulation applications.
