Subject: [ruby-talk:6628] Why is WeakRef#__getobj__ missing from the pickaxe book?

I notice that the discussion of WeakRef from the pickaxe book
has this example:

----
gcWasDisabled = GC.disable
if ref.weakref_alive?
  # do stuff
end
GC.enable unless gcWasDisabled
----

My question is, isn't it a better idea to just get a real reference
to the object using __getobj__?

----
if ref.weakref_alive?
  real_ref = ref.__getobj__
  # do stuff
  real_ref = nil
end
----
