since you are using the function in an if..then, it cannot operate<br>
(easily) upon sequences, however, it can be easily adapted to<br>
work with sequences and objects (just change the declarations<br>
from atom to object)<br>
the conditional testing would change tho, as you would be<br>
returning sequences of true/false values...<br>
