(** Weakest preconditions [WP e @ s ; E {{ Φ }}] have an additional argument [s]
of arbitrary type [A], that can be chosen by the one instantiating the [Wp] type
class. This argument can be used for e.g. the stuckness bit (as in Iris) or
thread IDs (as in iGPS).
For the case of stuckness bits, there are two specific notations
[WP e @ E {{ Φ }}] and [WP e @ E ?{{ Φ }}], which forces [A] to be [stuckness],
and [s] to be [NotStuck] or [MaybeStuck]. *)
