The D2 version of this code never compiled without error.

struct S {
    int x;
    template T(int val) {
        enum S T = { x: val };
    }
}
const x = S.T!(0);

It fails to compile because init.c, StructInitializer::toExpression() returns
NULL if any of the fields have names ( if (field.data[i]) goto Lno; )
And this is just because it's never been implemented.
