The -preview=rvaluerefparam flag isn’t directly relevant to 
replicating std::move in D. It enables efficient parameter 
passing with rvalue references but isn’t required for typical 
move semantics in D. Instead, D provides simpler, explicit 
mechanisms for similar functionality without adding the 
complexity of C++'s rvalue reference features.
