You could use the fact that <> opens the files for you: 

#!/usr/bin/perl
use warnings;
use strict;


# This is a program which reads in a list of file names from the comma
+nd 
# line and prints which files are readable, writable and/or executable
+,
# and whether each file exists.

while ( <> ) {
    print "$ARGV is readable!\n" if -r ARGV;
    print "$ARGV is writable!\n" if -w ARGV;
    print "$ARGV is executable!\n" if -x ARGV;
    print "$ARGV exists!\n" if -e ARGV;

    close ARGV;
} # end while
