Well, that is more or less what I meant by "do not play well together".

For C++ exceptions things are more or less under control, but I find
it almost very hard to write safe bindings in C++, so that Lua errors
would not get past C++ stack management. Looks like (almost) every Lua
function that C++ calls should be pcall-ed. I do not think that this
will be particularly fast.
