Thank you! That worked nicely!

Even if you can't use C++17, it still works like this:
if (not std::is_same::value)
if (dynamic_cast(this) == nullptr)

--- Comment #7 from Jonathan Wakely ---
if constexpr (not is_same_v)
if (dynamic_cast(this) == nullptr)
throw Exception("Bad callback");

Is there a cleaner way to can work around this than duplicating the affected
methods? I tried adding a #pragma, but that breaks older versions of gcc that
don't have -Wnonnull-compare.

Basically `dynamic_cast(this)` becomes just this if `T == Object` here and
then we warn because this is compared with nullptr.
