auto p = cast(void*) c; works if there is no alias this;. Implicit conversion
rules are irrelevant, because this is an explicit conversion. Therefore, I
think this is definitely a bug, because adding alias this should never disable
features to work, it should only be considered if the code would not compile
otherwise.
