// A context class doesn't do much by itself. We just use it to provide a
// virtual destructor so we can store a bunch of shared_ptrs in the same
// container and rely on RTTI in the layer context. It also deletes the copy and
// move constructors for derived classes implicitly, and that's pretty much it.
//
// We _could_ do something weird and complicated where we define virtual pure
// hashing and equality functions so we can store them in an unordered_set, but
// it's just unnecessary complexity and doesn't allow us to perform 'do you
// exist' lookups without creating an object.
