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;
