Is there an equivavlent to C# boxing in D?

[IGotD-]

If you want to store a value type on the heap in D you just use 
"new" and a pointer to the type. The same thing in C# would be to 
wrap the value type into an object. However when you do that 
automatic conversion without a cast seems not to be possible (C# 
also have a dynamic type that might solve that but more heavy 
weight).

Is there a possibility to wrap a value type in D around the base 
object class that is otherwise used as the class reference type? 
Would this be a way to use D without raw pointers for heap 
allocated value types?
