To Perl, @ARGV is just another array. It has some special features but
can be assigned values just like other arrays. You can use it to do
tricks, like set a default file list:
# Default file list is all text files
@ARGV = glob( '*.txt' ) unless @ARGV;
# Read the files
while( <> ){
chomp;
# ...
}

Programming is as much about organization and communication
as it is about coding.
I like Perl; it's the only language where you can bless your
thingy.
