 No it's ok, i am happy with that, if i really want, i can merge these 2 
methods:

def foo()
   puts 'test'
end

def function?(function_name)
   return true if private_methods.include?(function_name)
   return true if methods.include?(function_name)
   return false
end


puts function?('foo') => true
puts function?('notfoo') => false
puts function?('puts') => true

It's nice to learn a new language like that, thank you so much (and 
sorry for my  poor english)
:)
