Subject: Why was the object_id for true and nil changed in ruby2.0?

irb(main):001:0> true.object_id
=> 20
irb(main):002:0> false.object_id
=> 0
irb(main):003:0> nil.object_id
=> 8

The values for true and nil were respectively 2, 4 in 1.9.3 and 1.8.7,
but have been changed to 20, 8 in ruby2.0.0 - even though the id of
false remains the same i.e. 0 and the ids for Fixnum maintains the same
old 2n+1 pattern.

What's the reason behind this object_id change?

Why was this change made? How is this going to help developers?
