Subject: [ruby-core:39772] ObjectSpace.reference_form(obj) #=> references_array

Hi,

I wrote a patch of ObjectSpace.reference_form(obj).  This method returns
references that this object has.

example:
require 'objspace'

h = {'a' => [1, 2, 3], 'b' => Object.new}
p ObjectSpace.reference_from(h)

#=>

{76577650=>Hash, 76559320=>"a", 76559360=>[1, 2, 3], 76559310=>"b",
76559340=>#<Object:0x92067d8>}

Hash keys are object id and values are objects themselves.


Patch:

How about it?  Good name is also welcome.
