Good point.  It is the only predicate operator that does not have a 
negative syntax.

By predicate, I mean an operator that typically is used on other than 
true/false and returns true/false.  Relations are good examples.  Uh, 
look at the logical operators in "Transcript Language Dictionary" and 
skip and/or/not.
