perlcritic投诉以下代码,一些样板DBI的东西工作完美,应该
croak而不是
die：
# Connect to database my $db_handle = DBI->connect( $url,$user,$password ) or die $DBI::errstr;
所有这一切,虽然死了似乎对我来说很好.
我会想到一个武士的Perl战士,呱呱呱呱.able able able able when when……..笑话分开
为什么要cro ak而不是死？
没有注意perlcritic’s的建议有什么后果？

You use die when the error is something you or your code didn’t do right. You use croak when it’s something your caller isn’t doing right. die “error: $!” indicates the error is on the line where the error occured. croak “error: $!” indicates the error is on the line where the caller called your code.
