Hi Bruno, > So, why is there no setf in picolisp?
The answer is simple: It does not make sense. PicoLisp is a pure interpreter, and what 'setf' does is setting the value of what the expression *would* return. I'm not fit in CommonLisp, but (setf (car X) 7) means to set the CAR of the cell pointed at by X to 7. So a compiler analyzes the argument (car X), and compiles (set X 7) # in PicoLisp Similarly, (setf (get 'X 'a) 7) compiles to (put 'X 'a 7) There is a 'setf' function in PicoLisp (meant as a joke) in misc/setf.l ☺/ A!ex -- UNSUBSCRIBE: mailto:picolisp@software-lab.de?subject=Unsubscribe
