> Why would you do such a thing? A hash value is a single 64-bit slot, no need to add the memory consumption of a whole dictionary and the runtime cost of a LRU eviction policy when you can simply cache the hash in the object itself (like we already do for strings)...
It was a joke (I think). Taking into account the fact that LRU cache
uses a hashtable and need to calculate the hash of arguments (i.e., the
Decimal self) to get the cached value of hash. |
