And what would happen if you did:
huey = Nephew.new
duey = huey
luey = duey
some_array = [ huey ]
huey = nil

duey.raise_error #=> "Nephew...uhm...duey, luey, some_array[ 0
]?...raised an error."

A variable doesn't hold an object, it holds a reference to it. Many
variables (local, global, instance, and class) can all refer to the
same object.

If you have a symbolic name that is unique to an instance, pass that
name in when creating the instance.
