--- Comment #2 from Eyal <eyal at weka.io> ---
A small change to _load to make it actually use the incorrect "this" shows it's
still broken:

    import std;

    class Base {
        __gshared static Base function()[string] registry;
        static Base load(string name) {return registry[name]();}
    }

    class Child: Base {
        shared static this() {
            registry[__traits(identifier, typeof(this))] = &_load;   // <<<
this shouldn't compile
        }

        int x = 1;
        Base _load() {
            assert(x == 1, x.text);     //
core.exception.AssertError at dtest.d(15): 1970086008
            return new typeof(this);
        }
    }

    void main() {
        auto inst = Base.load("Child");  // segfault
    }
