Please cache the hashCode #126

Closed zajac closed 2 years ago

zajac commented 2 years ago

I think, hashCode could and should be cached for persistent data structures.

randomnetcat commented 2 years ago

hashCode can't be cached if the elements of the container are mutable, because the hashCode could then change without the container knowing.

You're correct, it would not be correct thing to do on the library level.
