Comment (by simonpj):

 Sorry I think I was mixed up.  A `foreign prim` is always `unsafe`, isn't
 it.  And you are only proposing to add `Any` as a possible result for
 `foreign prim` not for other `foreign` declarations, correct?

 So my third bullet is irrelevant.

 There's a missing close-paren in the (welcome) doc fix.

 Simon
