overriding alias symbols

[Superstar64 via Digitalmars-d-learn]

I'm trying to use mixin templetes to provide generic default 
implementations.
Something like this:
---
abstract class MyAbstractClass
{
     void myAbstractMethod();
}

mixin template defaultImplentation(alias Method, T...)
{
     override void Method()
     {
     }
}

class MyClass : MyAbstractClass
{
     mixin defaultImplentation!(myAbstractMethod);
}
---
Anyone have any ideas?
