Saving CLOS objects

Question

Saving any Common Lisp structure object to a file (readably) seems relatively straightforward with something like

(defun save-structure-object (object filename)
         


        

Answer 1

Closer to MOP allows one to avoid the dangerous tangle of read-time conditionals in the post you refer to. Generally speaking, using an OOTB solution that many people use is safer than a random ad hoc hack - your own or someone else's.

Before closer-mop was around, I wrote my own CLOS/MOP compatibility layer and CLOS object i/o. I suggest that you use it instead of the code in the SO answer you reference.
