To avoid having to use the Object class directly you can make an base class of the class template.

Like:

```
abstract class MyClass {}
abstract class MyClassImpl(T)
{
public:
    @property const(T) value(){return _value;}
    @property void value(T val){_value = val;}
 ...
   private:
    T _value;
 ...
}

MyClassInt and float inherits from MyClassImpl
```

And use it like:

```
void main() {
   MyClass[] objs;
   objs ~= new MyClassFloat();
   objs ~= new MyClassInt();
}
```

I would rather go with an interface than a base class.
