Sounds to me that Class::Singleton is exactly what you are after.

Deriving from that class will ensure that only one instance of your class will be returned:

package Grok;
use vars qw(@ISA);
@ISA = qw(Class::Singleton);

package Main;
my $one = Grok->instance();   # returns a new instance
my $two = Grok->instance();   # returns same instance

Hope this helps.
