If you take ikegami's idea one more step. You can enforce the variable name and save a little typing. However you get odd syntax. 
{
    package Foo;

    sub new {
        my ($class, $id) = @_;
        my $self = { id => $id };
        my ($package) = caller;

        ${$callpkg."::".$id} = bless $self, $class;

        undef;
    }

    sub method {
        my ($self, $name) = @_;
        print $self->{id}, "\n";
    }
}

Foo->new('one');
Foo->new('second');

$one->method;
$second->method;

This does not have the same syntax, but does get you the same result with about the same number of words. And you get pretty good error detection.
