This variant of RefPerSys uses libgccjit (see https://gcc.gnu.org/ and https://gcc.gnu.org/onlinedocs/jit/ ...) with a simple GNU readline interface.

Intuition

Code quickly something which is able to load and dump a persistent state in textual format (probably ours) and modify or generate some C files.

We need a readline interface and the ability to extract and modify some C files.

As soon as possible provide some libgccjit code generating binary code (and doing so at load time).

Requirements

For Debian stable:

# apt install zlib1g-dev
# apt install libunistring-dev
# apt install libgccjit-12-dev
# apt install libbsd-dev
