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?
