It is usually a good idea to use the $class = ref($class) || $class so a new object can be created from an existing object.

use strict;
use Data::Dumper;
package MyClass;
sub new {
    my ($class, $foo) = @_;
    print __PACKAGE__ . "->new called with $class, $foo\n";
    $class = ref($class) || $class;
    print "\$class is now $class\n\n";
    my $self = {foo => $foo};
    return bless $self, $class;
}
package main;
my $obj1 = MyClass->new('fooval1');
my $obj2 = $obj1->new('fooval2');

print Dumper($obj1, $obj2);

__END__

Outputs:

MyClass->new called with MyClass, fooval1
$class is now MyClass

MyClass->new called with MyClass=HASH(0x15d54bc), fooval2
$class is now MyClass

$VAR1 = bless( {
                 'foo' => 'fooval1'
               }, 'MyClass' );
$VAR2 = bless( {
                 'foo' => 'fooval2'
               }, 'MyClass' );
