The following shows that alias cannot be used to override a function that is
requested by an interface.
luckily the mixin does work, but I think that also the alias version should
work... (I find it cleaner)
I tested both in D1 and D2.
{{{
interface II{
    void f(int);
    void f(double);
}

template pr(T){
    void f(T i){
        // do something
    }
}

class A:II{
    void print(T)(T i){
        // do something
    }
    version(works){
        mixin pr!(int);
        mixin pr!(double);
    } else { // fails
        alias print!(int) f;
        alias print!(double) f;
    }
}
}}}
