Currently I'm exploring possibilities of using `:before-while'
instead of `run-hook-with-args-until-failure'.
IIUC, it can be used to replace hooks, so that for example,
when someone wants to put an additional function on `find-file',
it's possible to use `add-function' instead of appending
that function to `find-file-hook' (or `find-file-hooks'
that is an obsolete alias of `find-file-hook').
But in case of `isearch-filter-predicate', I don't understand
where and on which function to put additional predicate functions.
`isearch-filter-predicate' is a variable, not a function,
so it can't be used for the PLACE argument of `add-function'.
What I'm trying is:
(defvar isearch-filter-predicate nil)
(add-function :before-while isearch-filter-predicate (lambda (b e) (message
"b")))
(add-function :after-while isearch-filter-predicate (lambda (b e) (message
"a")))
(funcall isearch-filter-predicate 1 2)
This fails with the error: (void-function nil)
