Array/collection of templated class

[BCS]

Might this work?

abstract class Foo
{
	abstract TypeInfo TypeOf();
}

class FooT (T) : Foo
{
	public this (T a_value) { p_value = a_value; }

	public T value () { return p_value; }

	TypeInfo TypeOf() { return typeid(T); }

	private T p_value;
}

void main ()
{
	Foo[] arr = new Foo[3];

	arr[0] = new FooT!(int)(123);
	arr[1] = new FooT!(char[])("hello world");
	arr[2] = new FooT!(Object)(arr[0]);
}
