Perl::Critic::Policy::InputOutput::ProhibitBacktickOperators
Backticks are super-convenient, especially for CGI programs, but I find that they make a lot of noise by filling up STDERR with messages when they fail. I think its better to use IPC::Open3 to trap all the output and let the application decide what to do with it.
use IPC::Open3; @output = `some_command`; #not ok my ($writer, $reader, $err); open3($writer, $reader, $err, 'some_command'); #ok; @output = <$reader>; #Output here @errors = <$err>; #Errors here, instead of the console
This policy also prohibits the generalized form of backticks seen as qx{}.
