Well this is a pedantic issue. vstack is deterministic but its arguments are random so practically it
defines a random distribution.

this might be relevant to users of blog, so I cc'ed Rugs. (we need to have
a seperate mailinglist for dblog)

No.

1. Only use ~ for Distribution. Always use = for fixed
2. Vstack is a fixed function.
   We used to call it nonrandom function (internally it is), but it confusing
   therefore it was renamed.
   Fixed function means it has the same interpretation, i.e. given a same
   argument value, its value is always the same in any possible world.
