3-arg open is considered more secure than 2-arg open, as perl won't be looking to change it's behavior based upon any special characters (such as < > |) (update: in the filename). Since 3-arg open has no default (you can't leave the second arg undefined), you must explicitly indicate "open for read-only". Finally, some people simply like to be explicit. Why would you write 
foreach my $apple (qw(McIntosh Empire Gala)){ $apple }

When this would do just fine 
foreach (qw(McIntosh Empire Gala)){ $_ }
