I'm not sure why this ticket has been reopened, but if it's because of 
the following comment, this ticket can be closed, because the request 
has already been rejected in #7213.

Kosaki-san, why did you reopen this ticket?

Bug #3422: Object.const_get(:A, false) can access BasicObject::A

=begin
 From the documentation of Module#const_get(sym, inherit=true):

   If the constant is not defined or is defined by the ancestors and 
inherit is false, NameError will be raised.

 Yet, this works fine:

   BasicObject::A = 1
   Object.const_get(:A, false) # => 1

 While I haven't tested it, I believe the attached patch should fix the 
issue.
