Word description
The f parsing word adds the f object to the parse tree, and is also the class whose sole instance is the f object. The f object is the singleton false value, the only object that is not true. The f object is not equal to the f class word, which can be pushed on the stack using word wrapper syntax:
f ! the singleton f object denoting falsity \ f ! the f class word
