// Bool can be embedded in a struct to provide all the methods that
// have fixed output for any int-kinded nodes.
// (Mostly this includes all the methods which simply return ErrWrongKind.)
// Other methods will still need to be implemented to finish conforming to Node.
//
// To conserve memory and get a TypeName in errors without embedding,
// write methods on your type with a body that simply initializes this struct
// and immediately uses the relevant method;
// this is more verbose in source, but compiles to a tighter result:
// in memory, there's no embed; and in runtime, the calls will be inlined
// and thus have no cost in execution time.
