Otherwise, you will trigger all SIGDIE handlers and, not surprisingly, Test::More has one.
Test::Builder, actually. To whit: 
$SIG{__DIE__} = sub {
    # We don't want to muck with death in an eval, but $^S isn't
    # totally reliable.  5.005_03 and 5.6.1 both do the wrong thing
    # with it.  Instead, we use caller.  This also means it runs under
    # 5.004!
    my $in_eval = 0;
    for( my $stack = 1;  my $sub = (CORE::caller($stack))[3];  $stack+
++ ) {
        $in_eval = 1 if $sub =~ /^\(eval\)/;
    }
    $Test_Died = 1 unless $in_eval;
};

I'm afraid that eval{} users have to be allowed the ease-of-coding advantage over die-handlers. The whole purpose of eval is to catch an exception; you shouldn't have to go through additional hoops to protect against an exception. Yes, there's a perl design botch, but eval{} shouldn't have to suffer for it. (As far as I know, $^S is working in newer perls, which should make things a little easier.)
