 (Revision 218) Forgive the unintelligent short summary--not really sure
 how to describe what's going on.  e.class.name is empty, but e.className
 has a value.  Also, e.nextObject fails.

 {{{
 irb(main):001:0> a = [1, 2, 3, 4, 5]
 => [1, 2, 3, 4, 5]
 irb(main):002:0> a.class.name
 => "NSCFArray"
 irb(main):003:0> e = a.objectEnumerator
 => #<#<Class:0x1af5030>:0x1aed820>
 irb(main):004:0> e.class.name
 => nil
 irb(main):005:0> e.className
 => "__NSFastEnumerationEnumerator"
 irb(main):006:0> e.respond_to?( :nextObject )
