Subject: class_eval() problem

Here is some code that works as expected:

def create_class
  Class.new
end

MyClass = create_class

MyClass.class_eval do
  def greet
    puts 'hi'
  end
end

obj = MyClass.new
obj.greet

--output:--
hi


Now here is a more complex version:

def create_class
  cl = Class.new

  cl.class_eval do
    yield
  end

  return cl
end


MyClass = create_class do

  def greet
    puts 'hello'
  end

end


obj = MyClass.new
obj.send(:greet)
#obj.greet   #private method -- NoMethodError


Why is greet() a private method?
