try these two examples:
$data[0] = \bless( {'data1' => 'foo', 'data2' => 'bar'}, 'TFB');
$data[1] = bless( {'data1' => 'foo', 'data2' => 'bar'}, 'TFB');
print $data[0] ."\n";
print $data[1] ."\n";
you'll see that only the second produces an object: the first produces a
reference to the object, which must be dereferenced before you can call
a method on it.

This is what happens when you call a method on a reference, rather than
the object itself.
