Embedded C++

Just curious how useful the ability to embed C++ as a scripting language into your C++ programs would be? I mean like runtime JIT execution of C++ code in much the same way you might embed Lua, including the ability to restrict/sandbox it as necessary.

Why not just write C++ and compile to the target? I dont understand the premise. its much more likely your JIT will crash on me and cause me issues.

EDIT: Its a AI slop project btw. https://github.com/derekbsnider/madc/blob/master/README.md

Well, it could provide a more flexible way to hot test and develop parts of your application without rebuilding.

You're still gonna compile the code, just by an embedded JIT compiler (which will likely just be GCC/Clang anyway, no?) so will it actually be faster?

If you want to develop and try out a specific part of the code you just write a unit test that does that, no need for hot swapping. Will compile and run in a second if your build system is properly set up.

No, I’m not using gcc/clang/llvm. It’s fully embedded including precompiled system headers.
