As far as I know, you're just not going to be able to define your own 
behavior for this syntax.  It's not a valid method name as per parse.y 
(tNEG is not valid for the "op" production).


You could always define a method called "not()", but it won't have that 
"magic" flavor to it (not necessarily a bad thing, IMO).
