This probably won't work. What would you return exactly? Also, there's 
plenty of chance that the return value could interfer with the regular 
return values of that function... This will never be possible without work 
done by the module author so the return value plays nicely.

I'm not so sure either wether a function should only return error codes 
when it's called in non-fatal mode. I'd actually prefer to be able to 
enable/disable fatality for exceptions with a pragma without changing the 
interface (though that doesn't prevent having a mode where we'll have error 
modes), so that I can check exceptions when I want to....
