How would you do that the processing occured after foo has returned it's value ? If the print statement were in the function, then that would run before foo ended.

(defun foo (x y)
(prog1 (+ x y)
(do more processing after (+ x y) has been returned...))

That might work. May I ask how you would "print a value to the REPL" ?

Hello,

Is there a way in Common Lisp to continue processing data, after the REPL has returned a value - without starting a subprocess.

(defun foo (x y)
(prog1 (+ x y)
(do more processing after (+ x y) has been returned...))

Thank you.
