last cannot be used to exit a block which returns a value such as eval {} , sub {} or do {}
This is a bit ambigous. As a matter of fact, you can leave eval{}, sub{} or do{} using last. Have a look at this code: 
sub foo {
    last;
}

for (1..3) {
    print;
    do {
        eval {
            foo ();
        };
    };
}

It will print only "1". This is because the "last" will jump out of the for-loop, regardless of the surrounding sub{}, eval{} and do{}.
