You can sort of simulate "break" by calling a function which would do an
infinite loop. Using this with debug.sethook and you can step to the next
line.
As for jumping back or restarting you could maybe call the function you're
in again (using debug.getinfo) with the same arguments (using
debug.getlocal) but this sounds very hacky and unreliable. I'm not sure if
the debug library is 100% in luajit but I do know that you need to disable
jit compilation to get an accurate call stack.
