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.

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:

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";
