it is worth noting the "address" of the empty proc being 0 (NULL? :)

>> lambda{}
=> #<Proc:0x00000000@(irb):46>

but I do not understand why:
>> [lambda{}.object_id, lambda{}.object_id]
=> [-606913178, -606913188]

and:
>> lambda{} === lambda{}
=> true

? rdoc says that Proc uses Module's ===, shouldn't that check for object 
identity? what's going on?
