To add a different spin on the good answers already here, the call: 
    my $object = bless($reference, "MyClass");

[download]
does something like this: 
    sub bless {
      my ($reference, $class) = @_;
      $reference->{class_name} = $class;
      return $reference;
    }

[download]
and then whenever Perl sees something like this: 
    $object->some_function($arg1);

[download]
it transforms it into this: 
    $object->{class_name}::some_function($object, $arg1);

[download]
which in this case would translate into: 
    MyClass::some_function($object, $arg1);

[download]
There's a little more to it than that, to support inheritance and such, but that's the general idea.
