Is is possible to get a named tuple from a struct type?

E.g.:

struct S { int foo; string bar; }

S s;

S.tupleof t; // S.tupleof is a tuple type, as opposed to s.tupleof,
// which yields a tuple instance

t[0] = 1;
t.bar = "2";

If not, I think it would be quite useful.

Even still, a way to describe tuple types as if it was a struct would also be useful:

tuple StructLike
{
int foo;

string bar;
}

StructLike t;

t[0] = 1;

t.bar = "2";
