Yes. --rf/--rc work for preloaded classes/functions.

Just a side question: will the information on preloaded userland classes an=
d functions be available via php --rc / php --rf commands?

hi Michael,

You made a great job developing ext-psi.

But anyway, I more like my own FFI implementation (at least because it's
simpler and it's mine).

FFI::load() in conjunction with preloading, would provide functionality
similar to PSI files loading on startup.

In the future, I would like to push ext/FFI into core and integrate it
with JIT (similar to LuaJIT way).

In any case, this thread is about preloading, that is interesting by
itself. FFI and JIT are the future scope.

Thanks. Dmitry.
