```
    Parameters:
    
    other - predicate
    
    Returns:
    
    positive integer (>0) if predicates are logically the same, negative integer (<0) if predicates are logically inverted (like a == 2 and a != 2) zero (0) if there is no knowledge about the two or if they are independent

default Object[] toArray(IntToValue values)
```
    A convenience method to convert evaluator's arguments to object array.
    
    Parameters:
    
    values - evaluator's arguments as a functional interface
    
    Returns:
    
    arguments as an array
