Just wanted to check, if I've said "use fatal": will that "err 0" DWIM,
That depends what you mean. ;-)
Under "use fatal" you'll get an exception if you don't provide any args.
or will the fatalness win?
The fatalness will win.
Would I need to write
Yes. :-)
And what you'd need to write would be:
$sum = (try{ [+] @values } err 0);
