No.  For

  class Foo {} foo;
  auto& return_auto_ref() { return foo; }
  auto r6 = return_auto_ref();

the "getAs<AutoType>()" version will skip the function body and generate an error message on use, but "FD->getReturnType()->getContainedDeducedType()" works fine (will not skip the body, as it should here). OK, so now I have a rough idea what the "Contained" was referring too :)
