I'm working on something similar to the construct devised in the MPL book Section 9.5 (class composition). Some objects in the composed type might require initialization. I've solved this problem.
However, in solving that problem I've now required that any type going into the composition must be copyable. However, since the original composition code doesn't make this requirement I've been trying to find a way to retain the ability to contain types that are non-copyable. [snip]
So, I guess you've looked at the other container types in boost, such as fusion's vector: http://www.boost.org/doc/libs/1_46_1/libs/fusion/doc/html/fusion/container/v... and found them lacking in this regard. IOW, with these other container types, all the contained types must be copyable? -Larry
