Soo, yeah. I'm studying common lisp, and coming from picolisp setf confused me at first. The concept does not seem to appear on picolisp, and I wondered why its not there.
The only reference I could find was this: https://www.mail-archive.com/picolisp@software-lab.de/msg03604.html it mentions that it "violates the spirit of how lisp functions evaluate their arguments", but no more comment is made. I hope I'm forgiven if a flame war starts, but I'm trying to understand what makes a good lisp. So, why is there no setf in picolisp?
