| * `[[n,[not,Operator]],[Variable1,Variable2]]` where `Operator=is` or `Operator="="` e.g. `[[n,[not,is]],[[v,a],1]]` returns true where `[v,a]` must be instantiated (not empty) and can equal 2. | |
| * `[[n,[not,Operator]],[Variable1,Variable2]]` where `Operator=">"`, `Operator=">="`, `Operator="<"`, `Operator="=<"` or `Operator="=\="` e.g. `[[n,[not,>]],[3,2]]` returns false. | |
| * `[[n,[not,member]],[Variable1,Variable2]]` e.g. `[[n,[not,member]],[["a","b","c"],"d"]]` returns true. | |
| * `[[n,[not,head]],[Variable1,Variable2]]` e.g. `[[n,[not,head]],[["a","b","c"],"a"]]` returns false. | |
| * `[[n,[not,tail]],[Variable1,Variable2]]` e.g. `[[n,[not,tail]],[["a","b","c"],["b","c"]]]` returns false. | |
| * `[[n,[not,append]],[Variable1,Variable2,Variable3]]` e.g. `[[n,[not,append]],[["a"],["b","c"],["a","b","c"]]]` returns false. | |
| * `[[n,[]],[Variable1]]` e.g. `[[n,[]],[[v,a]]]` returns `[v,a]=[]`. | |
| * `[[n,""],[Variable1]]` e.g. `[[n,""],[[v,a]]]` returns `[v,a]=""`. | |
| * `[[n,"_"],[Variable1]]` behaves similarly to _A in Prolog e.g. `[[n,"_"],[[v,a]]]` returns true. | |
