Of course it's possible! There's even a module on CPAN to do it: Class::Singleton.

However, a singleton is really more of a design pattern, so there's a lot of ways to implement it. Rolling your own isn't that hard: 

package MyClass;

my $instance;
sub get_instance {
  unless ($instance) {
    $instance = ...; # instantiate instance here
  }
  $instance;
}
