Great!

It looks like the improvements to CHAR= and STRING= have a significant
impact on my CL-PPCRE stuff. Here are some examples:

(defun tester (scanner string n)
  (loop for i of-type fixnum below n
        do (cl-ppcre:scan scanner string)))


(let ((s (make-string 10000 :initial-element #\a)))
  (time (tester (cl-ppcre:create-scanner "a*") s 1000))
  (time (tester (cl-ppcre:create-scanner "(aaaaaaaaaa)*") s 1000)))

  (time (tester (cl-ppcre:create-scanner "a*") s 1000))
  (time (tester (cl-ppcre:create-scanner "(aaaaaaaaaa)*") s 1000))
  (time (tester (cl-ppcre:create-scanner "a*foobarbaz") s 1000))
  (time (tester (cl-ppcre:create-scanner "(aaaaaaaaaa)*foobarbaz") s 1000)))
