`Pattern` is intended to pilot some changes I would like to apply to all our sum types: - The alternatives are expressed as derived classes rather than members of a `std::variant`. - The alternatives are classes in the [style guide sense](https://google.github.io/styleguide/cppguide.html#Structs_vs._Classes), meaning they can have invariants, but can't have public data members. - Creating an object is expressed using a constructor rather than a factory function. - Accessing an alternative is expressed as a cast (using LLVM's RTTI system) rather than `std::get` or a `Get` method.
