If I define a method in Ruby, does it belong to any class?

Question

I have feeling, that if one defines a method

def test
  puts 'Hi'
end

then there is a class to which this method belongs to (i.e. Unknown#test). So one probably has a possibility to list all methods defined "outside" of other classes. Or there is another way to do such listing?

Answer 1

If you define a method outside of any class, it will become a private method of the Object class.
