irb(main):001:0> class MyClass
irb(main):002:1> def self.bar
irb(main):003:2> p 'bar'
irb(main):004:2> end
irb(main):005:1> end
=> nil
irb(main):006:0> MyClass.bar
"bar"
=> nil
irb(main):007:0> class MyClass
irb(main):008:1> class << self
irb(main):009:2> private :bar
irb(main):010:2> end
irb(main):011:1> end
=> #<Class:MyClass>
irb(main):012:0> MyClass.bar
NoMethodError: private method `bar' called for MyClass:Class
        from (irb):12
irb(main):013:0>

So to summarize the above, you need to go inside the singleton class for
MyClass to make any singleton methods private.
