Does this help 

use strict; use warnings; 
sub foo{
  return (0, 1);
}

my $ct=0; 

{
print "\nct:".$ct++."\n"; 
my $var = \(foo());  # $var is not a reference to the array (0, 1). bu
+t to the rightmost scalar  
print $var."\n"; 
print $$var."\n"; 
} 
{
print "\nct:".$ct++."\n"; 
my $var = (foo());  # $var is the rightmost of list 
print $var."\n"; 
} 

{
print "\nct:".$ct++."\n"; 
my ($var) = (foo());  # $var is the leftmost of list 
print $var."\n"; 
} 
{
print "\nct:".$ct++."\n"; 
my $var = [foo()];  # $var is array reference 
print $var."\n"; 
}
