 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.
