`iInv N as (x1 ... xn) "ipat" "Hclose"`

for closing the invariant is put in a hypothesis named

`iInv (N with "selpat") as (x1 ... xn) "ipat" "Hclose"`
: open the invariant
`N`
. The selection pattern
`selpat`
is used for any auxiliary assertions
needed to open the invariant (e.g. for cancelable or nonatomic
invariants). The update for closing the invariant is put in a hypothesis named
`Hclose`
.
