Use class template as a type

[dm via Digitalmars-d-learn]

Hi.
Is it possible to write in D something like this?

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

class MyClassInt: MyClass!int
...

void main()
{
  MyClass[] someArray;
  someArray ~= new MyClassFloat();
...

  someArray ~= new MyClassInt();
...

  foreach(myClass; someArray)
   if(typeid(myClass) == typeid(MyClassInt))
    myClass.value = 999;
   else
    myClass.value = 123.45f;
...

}
```
When I trying to compile code like above I got
Error: class MyClass(T) is used as a type.
