Sorry, I'm probably missing something, but I don't understand how this
would work. Since each function would only be modifying their own local
STRING variable, not the one that will actually be killed... Unless it's
something like
[in kill-region]:
(let ((string (delete-and-extract-region beg end)))
(run-hook-with-args 'before-kill-functions beg end #'string)
...
Then the hook function would have to set the string by
(defun foo-function (symbol)
(set symbol "replacement string"))
But that would be ridiculously arcane.
