I am writing a piece of code to sanity check various documents. I am currently writing a test to require a field to be non-empty if it is required. I was worried that if did not force grep into a scalar context. Should the following work as expected: 

my %required_column =
    (
     organization => [qw(0 1 2 4 6 7 8 12 15 16 17 18)],
     contact      => [qw(0 1 2 3)],
     service      => [qw(0 1 2 3 4 5 6  7  10 11 )],
     faq          => [qw(0 1 2 3 5 )],
     literature   => [qw(0 1 2 11 12 13)]
     );


sub sanity_check {

    my ($file, $column, $col_count) = @_;
    my $file = basename $file;
    $dcr_type = Gendcr::determine_dcr_type($file);
    if (not length($column)) {
    return if grep { $col_count eq $_ } @{$required_column{$dcr_type}}
+;
    }
       
    
}
