(defun save-a-string (string function value stream)
(declare (ignore stream))
(dovector (char string)
(when (char= char #\")
(funcall function value #\\))
(funcall function value char)
(defun save-a-string-to-an-open-stream (string stream)
(save-a-string string a b stream)))
;(save-a-string-to-an-open-stream "ddddd" *standard-output*)
I have something like this for fixnums too, but you might as well call
print-object for numbers
Fixnums are pretty easy, but floats are a bit harder. I have some code
that does pretty well for floats.
Another thing to try is FORMATTER. In some Lisp's, like Allegro, it's
really just a call to format, but in MCL it looks like its trying to do the
right thing. I haven't timed it though.
You should also try WRITE.
