Is there a way to shallow copy an object when the type is

A generic class copy function would require accessing private
fields, so a clean per-attribute class copy is impossible.
Doing a bitwise copy might work except for the synchronization
mutex pointer.
Can you elaborate on why you need this?
To implement a copy/paste/duplicate functionality in a game
editor. I have an entity-component system, to duplicate an
entity, all it's components need to be duplicated. I have many
many components, I don't want to rely on manually writing copy
methods for each, it is too error prone. There are only a very
few that need special copies, almost all can get by with a simple
shallow copy. I would like a generic way to do that shallow copy.
How does D not have shallow copy? Seems like a very basic
functionality...
