I think what you want is to add a singleton method to the current object
(self), but one which is able to reference the local variable 'pp'. I'd be
interested to know how to do that, too.

You can do this:

    self.class.instance_eval { define_method(:pp, pp) }

    pp(9)  # >> 10

but that adds pp to the class, rather than the current object.
