This code compiles using DMD e0cdcac, but failed as expected using DMD 2.058:
---
template B(T) {
  mixin(
    {
      foreach (name; __traits(derivedMembers, T)) {}
      return "struct B {}";
    }()
  );
}

struct A {
  pragma(msg, "A: ", __traits(compiles, B!(typeof(this))));
  B!(typeof(this)) c;
  static if (nonExistent!()) {}
}

auto d = A.init.c;
---

(output is ğA: falseĞ, but apparently the template can be instantiated
afterwards)
