I think that ENUMQUERY() should still return a valid ID for the lookup  
attempt.

Then, I think the "getnum" option could be updated to return a  
negative value if an error occurred, as opposed to 0 for when the  
result was just empty.  When an error has occurred, a new option like  
"reason" could be added to get a string based representation of the  
failure.
