[boost] [fusion] Can you store noncopyable items in a fusion map?

Can you store non-copyable items in a fusion map?  I'm just using it to 
map types to ptr_containers and I don't want to copy it ever.

Windows works just fine but another compiler complains about not being 
able to create the implicit copy constructor for fusion::map.

The documentation implies that a fusion::pair must be assignable and 
copyable in its expression semantics but I think this may be overly 
restrictive.

Looking at the code it seems that I may need to make a noncopyable_map 
and noncopyable_pair to achieve this goal.

Is this the easiest way?

Thanks,
