TS Typings: Class properties should be of type Message, not Message$Properties

[foxdavidj]

message FooMessage {
  bool my_bool = 1;
  repeated BarMessage bars = 2;
}

message BarMessage {
  string my_string = 1;
}

Right now FooMessage.bars is of type BarMessage$Properties[] which has the unfortunate side-effect of FooMessage.bars[0].my_string being of type string|undefined when it should be of type string.

1. Would changing the typings from Message$Properties to just Message be an acceptable fix? OR
2. Should we duplicate the Message$Properties interface and create two versions? One with optional props and one without optional props?

There is a new command line option --force-message in master now that does exactly this.

Works great. Thanks
