How does this differ from boost::compressed_pair ?
Well, compressed_pair applies to a pair and compressed_member applies memberwise. In a situation where you have more than two members compressed_member may compact better. Consider this situation: struct A {}; struct B {}; struct C : compressed_member<A> , compressed_member<A, 1> , compressed_member<B, 1> , compressed_member<B, 1> { }; Here, each A gets its address but the Bs can share those same addresses. I think applying the optimization memberwise may scale better for arbitrary tuples. Regards, João Abecasis
