how to get back an object from its id() value

Hi everybody,

I have a data structure (a tree) that has one constraint: I can only store
strings in this data structure.

To know if an object foo already exists in memory, I store "str(id(foo))" in
the data structure.
OK.

But how do I get a usable reference from the id value?
For example, if "foo" has a method "bar()", how can I call "foo.bar()"
from "str(id(foo))" (say, 149466208).

Thanks in advance,

Julien
