This is why you write:

try {
   my $good_result = $obj->validate;
   do stuff with good result
} catch {
   my $bad_result = $_
   do stuff with bad result
};

Or if you "do stuff" the same:

my $result = try { $obj->validate } catch { $_ };

Exception based control flow is very common and very useful. You can't ignore
it or forget about it unlike the pesky:

return $ok ? ($ok_ret) : (undef, $fail_ret)
