It would be nice if we could use:
- (3 Unable to render embedded object: File (in [2,3,4]) or (3 not in [2,3,4]) instead of () not found.(3 in [2,3,4]))
- also for instanceof
- It doesn't look like a big issue if it's just "!(x in ['x'])", but when the line is longer and more complex and when use together with other parenthesis, skipping one pair of parenthesis means a lot in code clarity. It's just like in SQL, we can add a NOT to NOT LIKE or NOT IN.
