Let’s consider the following code:

module M
  extend self
  def m_i 
    puts "m_i"
  end 
  def m
    puts "include? = [#{singleton_methods.include?(:m_i)}]"
    puts "call = [#{singleton_method(:m_i).call}]" rescue puts $!
  end 
end

it prints:

# include? = [true]
# undefined singleton method `m_i' for `M'

The method is listed under singleton_methods while the call to it via singleton_method raises an error.

You should compare singleton_methods(false).
