in reply to About the use of the plural form for the name of variables

I like to use the plurals for arrays when it refers to a collections of things, because an array can be a single thing: 
my @files;
my @file1 = qw{ /etc passwd root root 0644 };
my @file2 = qw{ /etc group root root 0644 };

push @files, \@file1, \@file2;
