Getting the name of an instance

[Mark McEahern]

Short answer:

What would you expect in the following scenario?

  p = MyClass()
  q = p
  p = None
  func(q)

I'd be curious to see an example of how you'd use this "getting the name of
an instance."

By the way, this topic seems to come up every once in a while.  Here's the
latest regurgitation:

[watch for wrapping]
