// The serialization format follows the Text format for Protocol Buffers of the
// `IRObject` message, with the following message definition:
//
// message IRObject {
//   oneof value {
//     uint64 i = 1;
//     double d = 2;
//     bytes s = 3;
//   }
//   repeated IRObject sub = 4;

//
// The protobuf definition does not allow putting `sub` in the oneof because it
// is repeated, but the C++ type enforces the invariant that only one field is
// set.
