Re^2: hash reference to itself

There is no object here, just class calls which might as well be package calls.

print MyPkg::name(), $/;
MyPkg::print();

You're right. Is this better? `#!perl use strict; use warnings; package MyPkg; sub new { my ($self, $name) = @_; my %hash = ( name => $name ); return bless \%hash; } sub print { my $self = shift; print "name: " . $self->{name}; } package main; my $obj = MyPkg->new('foo'); $obj->print();` [download]	[reply] [d/l]

Yeppers. Though I am not a fan of anything but a view layer (this would be `main::` implicitly here) doing output so `print` embedded in methods/subs is, to me, code smell. I understand it's convenient for examples but it can rub off on newbies as a good practice.	[reply] [d/l] [select]
