I'm a little confused about the following: clear,delete,destroy. My understanding is that clear is deprecated and delete is planned to be deprecated, so we should only ever use destroy (which deterministic calls the destructor but doesn't release memory).
Unique uses delete however in the destructor. Is that still guaranteeing deterministic destruction when the uniqued element is either a class or struct? (ie if the destructor has a file handle resource, will it be deterministically freed?)
