Are arrays and objects part of a unified type system? Specifically, if I do

void foo(Object x) {
    if (typeid(x) == typeid(Object[])) {
        auto a = cast(Object[]) x;
    }
}

I get a compilation error:

onlineapp.d(3): Error: cannot cast expression x of type object.Object to Object[]

What's the way to achieve the cast, which should be safe given the typeid check?

Thanks and regards,

Did you try templates? It seems easier:
