DMD allows you to derive a non-deprecated class from a deprecated class.  You
can even instantiate the derived class, and use it to access the deprecated
class's members, thereby bypassing the deprecation!

----------
import std.stdio;

deprecated class DepClass {
    void test() {
        writefln("Accessing what's deprecated!");
    }
}

class Derived : DepClass {}

void main() {
    Derived d = new Derived;
    d.test();
}
