// Pure assert == works
let tst_rw (x:int) =
  assert (
    (if x >= 0 then p else emp) ==
    (if x < 0  then emp else p)
  )

// Not so in Pulse?
```pulse
fn test2 (x:int)
  requires (if x >= 0 then p else emp)
  ensures  (if x < 0 then emp else p)
{
    rewrite (if x >= 0 then p else emp)
    as      (if x < 0  then emp else p);
}
```
