Re: Lua DSL in C++

Very interesting project! You could workaround this by partially implementing the lua.h (and friends) API with `extern "C"`, so that libraries can talk to you. You will need to still create a stack, but it would only be used by C code, when a call happens into a DSL function, you could completely sidestep the stack.

As for debugging, you could *probably* do some native stack unwinding, although that's gonna be very tricky...
