Really? So {a:1, a:2} would be a dict of length 2?
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?
