PHP's FFI support is a feature that's 2/3 there and isn't seeing improvements. It makes me miss Python's cffi.

Bet you don't miss Python's massively lackluster performance when compared to PHP though! Nb. I use both for diff things (good luck instrumenting ai stuff with PHP!) but the fact that I have to reach for C extensions for python to even get a basic loop to run at reasonable speed remains peculiar/scary for me.
