<div>
<pre>consider:
template <class T>
struct InherType : public UndefType {};
template <class T>
class TmplType {};
TmplType<InherType<wchar_t> > x;
MSVC is fine with this even though InherType inherits from a previously
unreferenced type.
Once you try to use the incomplete type, diagnostics are emitted.</pre>
