Comment (by viboes):

 Initially I didn't see the need to use base_from_member with a reference,
 as the referenced object is already initialized. IIUC you want that your
 class container_something should be able to be instantiated either with a
 Container and then copy it, or with a Container& and then store the
 reference. I find this usage a little bit bizarre. Could you tell me in
 which cases do you use Container and when you use Container&?
