IN() without parameter

It would be nice, if IN() without any parameter doesn't throw syntax error and return false instead. This would make easier writing scripts like DELETE / UPDATE ... WHERE (NOT) IN(?).

example:
SELECT 2 IN (0,3,5,7);
returns false

SELECT 2 IN ();
returns syntax error
false would be better

Also NOT IN() without parameter should return true. Optimizer also could replace this functions with true / false.
