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
This Policy is not configurable except for the standard options.
