�Eventually, I also think this will seque and integrate nicely into Mark Shannon's "shared-key dict" proposal (PEP 412).


I just noticed something in Guido's example. �Something gives me a strange feeling that using a variable as a key doesn't smell right. �Presumably Python just hashes the variable's id, or uses the id itself as the key, but I wonder if anyone's noticed any problems with this, and whether the hash collision problems could be solved by removing this?? � Does anyone even use this functionality -- of a \*variable\* (not a string) as a dict key?
