You can use this tool to automatically generate bindings to C libraries:

You can get quite close with interfaces and templates:

interface Foo
{
     void foo ();
}

template FooTrait
{
     void foo (); { writeln("foo"); }
}

class A : Foo
{
     mixin FooTrait;
}

class B
{
     void b () { }
}

class Bar : B, Foo
{
     mixin FooTrait;
}
