test case, w/o phobos

enum A; enum B; enum Dummy = 0; // <- Dummy needs to be 0

alias Seq(T...) = T;

@Seq!(A,B) struct Foo1 {}           // rejected
@Seq!(A,B, Dummy) struct Foo2 {}    // works because of dummy

static assert(is(typeof(__traits(getAttributes, Foo1)))); // fails but should
not
static assert(is(typeof(__traits(getAttributes, Foo2)))); // pk

void main() {}
