Thank you, nice article.
All the examples for singleton point to class methods and not instance ones. I wanted something like:
in reply to Re: Object singleton method
in thread Object singleton method
my $obj1 = Class->new;
my $obj2 = Class->new;
# definition of singleton method for $obj1 goes here ...
$obj1->singleton_method and print "It works.\n";
$obj2->singleton_method and print "It doesn't work.\n";
