Perl::Critic::Policy::InputOutput::RequireCheckedClose − Write "my $error = close $fh;" instead of "close $fh;".
This Policy is part of the core Perl::Critic distribution.
The perl builtin I/O function "close" returns a false value on failure. That value should be checked to ensure that the close was successful.
my $error = close $filehandle; # ok close $filehandle or die "unable to close: $!"; # ok close $filehandle; # not ok use autodie qw< :io >; close $filehandle; # ok
You can use autodie, Fatal, or Fatal::Exception to get around this. Currently, autodie is not properly treated as a pragma; its lexical effects aren’t taken into account.
This Policy is not configurable except for the standard options.
