Object.opEquals is not marked shared. You can't override a non-shared 
method with a shared one.

You need to remove override.

But... unfortunately, this may not work in practice. The opEquals 
handling for objects is pretty much screwed unless you have unshared 
mutable objects. I think it may work for const objects, but not in a 
good way.
