C++11's std::tuple includes a function std::tie that takes references to

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?
Not that I know of. But, Philippe Sigaud's dranges[1] library includes
a RefTuple[2], which should do what you want.
