It is

Python bindings ABI hashing (boost::abi_hash?) A duck-typed std::any (boost::virtual_any?) Reflection libraries! • Reflection is a really powerful language feature ☐ With great power comes great responsibility • Easier to write general-purpose / boilerplate-reducing libraries • Solve multiple
