Can I set the base class like this?

[Jack]

Can I pass the base class type thought template parameter? 
something like this:

class MyType { }

class A(T)
{
     void doSomething() { }
}

class B(T)
{
     void doSomething() { }
}

// this class shared stuff to deal with A and B
class C(T) : T!MyType
{
     void doSOmethingElse() { }

     override void doSomething()
     {
         doSOmethingElse();
         super.doSomething();
     }
}

then do something like this:

alias Foo = C!A;
alias Baa = C!B;

instead of:

class Foo : A!MyType
{
     void doSOmethingElse() { }

     override void doSomething()
     {
         doSOmethingElse();
         super.doSomething();
     }
}

class Foo : B!MyType
{
     void doSOmethingElse() { }

     override void doSomething()
     {
         doSOmethingElse();
         super.doSomething();
     }
}

note the body is the same, what changes is the base class. I'd 
like to avoid repeating myself when the body is the same and only 
the base class changes.
