A method and a function are the same thing. Also, check this out.

Toplevel methods are implicitly added as private methods of class
Object, so...

p self.private_methods.include?("foo") # => true

It's true, i try this differents ways :
in irb:>> def foo
puts 'test'
end
=> nil
methods.include? "foo

=> true
--------------------
in test file:
def foo()
puts 'test'
end

puts methods.include?('foo')

=> false
---------------------
So, now with your private_methods

def foo()
puts 'test'
end

puts private_methods.include?('foo')

=> true

Good job :)

But you don't really want that... ;)

You want respond_to? which Just Works everywhere.

No, it behaves the same, you will get a respond_to?(foo) false at the
main level.

And really, you
probably don't even want to be asking if a method is defined (depends
on your code), but usually there are better ways of doing things (like
unit testing).

All truth passes through three stages. First, it is ridiculed. Second,
it is violently opposed. Third, it is accepted as being self-evident.
Schopenhauer (attr.)

You have to pass a second parameter to respond_to? to include private
methods. ;)
