ref tuples

C++11's std::tuple includes a function std::tie that takes
references to the arguments and returns a tuple that maintains
the references to the arguments.
Along with the usual cases where you'd want reference semantics
it also enables this interesting construct for unpacking tuples.
int a, b;
tie(a, b) = make_tuple(1, 2);
assert(a == 1 && b == 2);
Is there any way to do something similar with std.typecons.Tuple?
