We have discussed a number of approaches to handle the let-binding performance and to handle sometimes-confusing behaviour of `case-fold-search'. Most of them had problems with breaking the existing behaviour or potentially causing unexpected side effects. Except the one I used in the patch. The messages you linked to discuss problems with _other_ proposed approaches. > ??? Then what were these about: > > https://debbugs.gnu.org/cgi/bugreport.cgi?bug=66117#199 This is about an idea to make let-binding the `case-fold-search' affect current buffer only, but never other buffers. What the patch does is different - it turns `case-fold-search' into an ordinary buffer-local variable, like the ones defined from Elisp. > https://debbugs.gnu.org/cgi/bugreport.cgi?bug=66117#217 > https://debbugs.gnu.org/cgi/bugreport.cgi?bug=66117#283 These two are about creating a new case-fold-search-override that ignores buffer-local bindings. Again, a different idea. > https://debbugs.gnu.org/cgi/bugreport.cgi?bug=66117#295 This was not about this patch, but about a more general problem of case-fold-search serving two purposes - user setting for interactive searches and internal regexp search switch. -- Ihor Radchenko // yantar92, Org mode contributor, Learn more about Org mode at .
