It is important to note that Perl OO does not have any "built in" concept of data. There is no default
Constructor and the
Destructor consists of a call to
DESTROY.
It might be more descriptive to rewrite Foo->new()->hello('test5');
as
bless(\sub {}, 'Foo')->hello('test5');
This just blesses a CODE_REF for fun. It could be a HASHREF or some other REF.
The only real difference between
'Foo'->hello()
and
bless(sub {}, 'Foo')->hello()
Besides the fact that the
blessed version can contain data, is that
just before the
blessed object is Garbage Collected,
DESTROY is called with it as the argument ($x->DESTROY).
UNIVERSAL
contains a DESTROY method, so it always exists.
