By the way, would it be safe to, er, redefine the error() function to

There are two misconceptions here. First, the error function does not
the interpreter, it only aborts the current chunk.
Ok. What precisely is a "chunk" then? I start my Lua application like
If anything unexpected happens in Main.lua, the interpreter exits,
right? I would like to avoid this. How?
Second, not all errors
are raised by calling error(). Actually, most aren't.
Ok... so... what should one do to handle errors in a more graceful
manner? If a native C module decides to unitarily trash the VM, so be
it. But if an exception emanate from a Lua piece of code, I would like
to be able to handle it one way or another so the VM keeps running. How
can I do that?
In a nutshell, I would rather not have the VM simply quit for random
reasons. I would much prefer to have the possibility to have a say in
deciding if a so called error warrant the termination of the VM,
chunked or not. What would be a good way to achieve this?
