That's what I thought initially, but the strings take most of the space in dict and I didn't feel like doubling the size.
You could write a string wrapper that changes comparison and hashing. I'm not sure that this (+ 1 (Python object + instance dictionary)) would use less memory than the other proposal (+ 1 Tuple + 1 String).
