Defining a (private) method at the "top" scope is equivalent to
defining a private method at the scope of the class Object. (The same
is true for defining/removing constants by the way ). For this reason
 I often felt it might be a good idea idea to get rid of the  "main" -
 it serves on  on apparent use anyway - and just replace it with Object 
- that the call  at the top scope

--
p self # would results in Object instead of the current"main"
--

---
def Object.method_added(sym)
    if private_methods.include?(sym.to_s) 
        puts "private instance method ##{sym.to_s} was added to class 
#{self}"
    end
    super
end

self.class   # => Object
def foo
  p 'foo'
end

public

def bla
end


class Object
    def blabla
    end
    private
    def bar
    end
end
--
resutls in
---
private instance method #foo was added to class Object
private instance method #bar was added to class Object
