Ok. What precisely is a "chunk" then? I start my Lua application like 
this:

lua Main.lua

If anything unexpected happens in Main.lua, the interpreter exits, 
right? I would like to avoid this. How?

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?

Cheers
