This is interesting. What if you want to have a language that uses
only immutable objects and garbage collection? Could smart pointers
address this problem?
Yes, garbage collection changes the picture entirely, with or without
immutable objects. But the original topic was cross-processs shared
memory, and I don't know of any cross-process aware garbage collectors
that support shared memory. Although such a thing could easily exist
without my knowledge.
