You really cannot leave eval{} with a last.
Oh yes, you can. But you will not only leave the eval but the loop around it, too. If there is no loop around that eval, you'll die—just like your code demonstrated. 
eval {
  last;
};
warn $@ || 'no error';

for (1) {
  eval {
    last;
  };
}
warn $@ || 'no error';

The output of the above code is: 
Can't "last" outside a loop block at x.pl line 2.
no error at x.pl line 11.

By the way, even if the code in my previous post had died in the eval{}, the loop would have continued and the output would have been 123.

(++ for you anyway, because you almost tricked me into admitting that you're right :)
