   `and` and `or` work because they are binary operations so you can write "if (a.and(b))".  `not` is a unary operation semantically.  So the way you have it you could have "if (a.not())".  Are you looking for "if (not(a))"?  For that, you could supply a DGM like this:
   ```java
   public static Boolean not(Object self, Boolean target)
   ```
   With this, you could write "if (not(a))" and "self" would the the object that is the implicit "this", which you can ignore.
