Re^2: Printing an element of a list not an array

Nice and thank you!

However, in one of the examples of intermediate perl there is a section in the package that don't use surrounding circular braces. Any idea why ?
See below code its working fine with out any braces surrounding the list, does it have to do anything with the return?

{
package MyDate;
use vars qw($AUTOLOAD);

use Carp;

my %Allowed_methods = qw( date 3 month 4 year 5 );
my @Offsets = qw(0 0 0 0 1 1900 0 0 0);

sub new { bless {}, $_[0] }
sub DESTROY {}

sub AUTOLOAD {
my $method = $AUTOLOAD;
$method =~ s/.*:://;
unless( exists $Allowed_methods{ $method } ) {
carp "Unknown method: $AUTOLOAD";
return;
}


my $slice_index = $Allowed_methods{ $method };

return (localtime)[$slice_index] + $Offsets[$slice_index];
}
}

MyDate->import; # we don't use it
my $date = MyDate->new();

print "The date is " . $date->date . "\n";
print "The month is " . $date->month . "\n";
print "The year is " . $date->year . "\n";

This is because when using `print` or `say`, there is ambiguity in what you're passing. Without the parens: `perl -w -E 'say (localtime)[1]' say (...) interpreted as function at -e line 1.` [download] `say` like `print` are both functions. perl just makes it convenient that you can omit a function's parens in most situations. `say` believes that the opening parens belongs to itself, like this: `say( localtime )[1] ;`, which is wrong. So if you look at it like this: `say( (localtime)[1] );`, it may become clearer as to what's happening. In most other cases, you can eliminate the parens: `my $x = (localtime)[1];` [download] or `return (localtime)[1];` [download]	[reply] [d/l] [select]
