Classes. C++ to D

[Adam D. Ruppe via Digitalmars-d-learn]

I'd make class A and class B into mixin templates instead.

mixin template A {
    string a() { return "foo"; }
}

mixin template B {
    string b() { return "bar"; }
}

class C {
    mixin A;
    mixin B;
}

If you still need class A and class B, just make a class that 
mixes in the template for them too.


Since the C++ methods aren't virtual, I imagine you don't really 
need a base class for them, but if you do want a virtual base 
class, make interfaces and inherit from as many of them as you 
need.
