I see this as the only possibility. It's not very nice though. This way user is required to include a header
each time he want to use a container. It gets even more confusing, because the trait class is supposed to 
be only an implementation detail. However this way, users either accept the inclusion of unwanted headers,
or they have to include specific header manualy. 

Typical now win solution :(
