There was a problem hiding this comment.
I don't like this "First part" thing, but can't figure out a nicer way of presenting it,
Suggestion for your criticism:
(* First subgoal:
from every memory in the original precondition (x = n),
the program y <- x + 1 leads to
a memory in the intermediate assertion. *)
and similarly for the second subgoal. (Also note that return no longer appears in the program at the point where seq is applied.)
