Subject: Re: [PHP-DEV] [mini-RFC] Disable opcache per script using

Ah, ok, this makes sense. Though usually such file would be rather small
and adding whole new directive just for it may not be that necessary, I
think.

Yes, that's what I am wondering too - how things defined directly in
preload file then will be treated? While file itself is not useful later
in server's lifetime, the things defined in it - like classes or
functions - can be?
