In my humble opinion it is a good idea to throw an exception when an error occurred. The caller is then free to either catch the exception (with eval BLOCK) and work with $@, or to not catch it have the error abort the program, printing out the error message.

For example you could do something along these lines: 


for (@users) {
    my $success = eval {
        add_account($_);
    };
    warn "Can't add user '$_': $@" unless $success;
}

This has the advantage over a plain return() that throwing the exception works the same if you call subs from add_account() and they detect an error.
