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";

You cannot get only the names as a tuple but you can implement something 
similar:

1. Loop through the tuple
2. Get the name of a field in the struct using the "stringof" property 
on the tuple
3. Slice of the name of the struct and some other unwanted characters

You can have a look at this method as well:

 also be useful:

     tuple StructLike
     {
          int foo;
          string bar;
     }

     StructLike t;

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