It was more for fun than profit ;) The OP gave  

[apple, dog, fork]

in his examples, and the "normal" no-nonsense approach using a list of 
strings would produce

['apple', 'dog', 'fork']

I was tempted to carry this even further with

>>> class Name(str):
...     def __repr__(self): return self
... 
>>> class Namespace(dict):
...     def __missing__(self, key):
...             self[key] = result = Name(key)
...             return result
... 
>>> fruit, pets, cutlery = eval("[apple, pear], [dog, cat], [fork, spoon]", 
Namespace())
>>> fruit
[apple, pear]

but resisted until now...
