To sum up, I need a way to make sure that all errors in Lua  (which
may happen in say lua_dofile() or lua_call()) result in a
std::exception being thrown (which I will catch in my C++ code).

If it is possible, it would really help the debugging if an
informative message were included in the exception (like: "Parsing
error at line 24 of file.lua").

Any help / comment is greatly welcome.
Use lua_pcall. If if fails, you can throw an exception yourself if you want to.
