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...
