Let em clarify what is happening here. Baz::foo is calling
super(), which calls Bar::foo, which is an augmented sub
that calls Foo::foo, then calls inner() which actually
then calls Bar::foo. Confusing I know,.. but this is
*exactly* what is it supposed to do :)

=cut

is($baz->foo,
  'Baz::foo -> Foo::foo(Bar::foo)',
  'got the right value from mixed augment/override foo');

Allow me to clarify this one now ...

Since Baz::bar is an augment routine, it needs to find the
correct inner() to be called by. In this case it is Foo::bar.
However, Bar::bar is in-between us, so it should actually be
called first. Bar::bar is an overriden sub, and calls super()
which in turn then calls our Foo::bar, which calls inner(),
which calls Baz::bar.

Confusing I know, but it is correct :)

is($baz->bar,
    'Bar::bar -> Foo::bar(Baz::bar)',
    'got the right value from mixed augment/override bar');
