If we should follow this form, then IS DISTINCT should be written as: x =! y This looks unusual, because JavaScript also follow != form. so I hope it will be easy to detect/implement != form, which I used to read as: negate the result of comparison
Postgres already allows != as a synonym for <>. I think having =! mean something subtly but significantly different is a terrible idea. At a minimum we would have to remove the synonym, which would be a backwards compatibility break.
