what he did is:

irb(main):005:0> a =
irb(main):006:0* class<<self
irb(main):007:1> self
irb(main):008:1> end
=> #<Class:#<Object:0xb7cf29a4>>

so now in a you have a class object. self is the current instance of the
class.
then with
a.instance_methods(false)
you can print all instance methods of self. the .sort only sorts them
alphabetically.
