This code fails when T is polymorphic

[lifflander]

std::unique_ptr<T> task(new U(1234));
auto ret = checkpoint::serialize<T>(*task);
auto out = checkpoint::deserialize<T>(std::move(ret));

@PhilMiller What do you think? Should we support this case?

Yes, I think we should support this case. It presumably works fine if task is serialized as a member of something else, and it's just s | task?

Since a PR for this just got posted, I'm looking at the example again, and I can't help but read that as kinda like slicing. Probably still good if it is made to work correctly, though. I'll look at the PR.
