proc and lambda?

yield

1. your own class as a key in hesh. listen carefully.

2. send(:momom)

3. 
See http://ruby-doc.org/core/classes/Hash.html

Hash uses key.eql? to test keys for equality. If you need to use instances of your own classes as keys in a Hash, it is recommended that you define both the eql? and hash methods. The hash method must have the property that a.eql?(b) implies a.hash == b.hash.

The eql? method is easy to implement: return true if all member variables are the same. For the hash method, use [@data1, @data2].hash as Marc-Andre suggests in the comments.

Add a method called 'hash' to your class:
class Foo
  def hash
    return whatever_munge_of_instance_variables_you_like
  end
end
This will work the way you requested and won't generate different hash keys for different, but identical, objects.

class Ololo
  def boo
    'boo'+object_id
  end
  def to_s
    boo
  end
end

 a = Ololo.new
 b = Ololo.new
 {a => 'aaa', b => 'bbb'}
