If you search the buffer text, then having syntax-table on that text is less surprising: after all, it only affects the text which has this property. But buffer-local case-table is much more subtle: it is in effect even if you match strings, not portions of buffer text, and only because some buffer _happens_ to be the current buffer when, say, string-match is called. > In the past, me and Mattias Engdegård even discussed a possibility to > incorporate case-fold-search flag into regexps directly > (https://debbugs.gnu.org/cgi/bugreport.cgi?bug=63225#74) > That way, things would be less affected by the buffer-locals. Indeed.
