I saw proto-files in the wild with message-expression ending in a semicolon. libprotoc version 3.21.4 compiles this fine.

Thanks for reporting this. Yeah, there are still little things like that where we differ from protoc, we'll get it right eventually.:) Should be an easy fix.

It looks like the fix in #213 doesn't work for tested structures. I'm getting the error on this example from onnx.proto3:

message TensorShapeProto {
  message Dimension {
    oneof value {
      int64 dim_value = 1;
      string dim_param = 2;   // namespace Shape
    };
    // Standard denotation can optionally be used to denote tensor
    // dimensions with standard semantic descriptions to ensure
    // that operations are applied to the correct axis of a tensor.
    // Refer to https://github.com/onnx/onnx/blob/main/docs/DimensionDenotation.md#denotation-definition
    // for pre-defined dimension denotations.
    string denotation = 3;
  };
  repeated Dimension dim = 1;
}

I guess the fix should also be trivial, but I'm not sure what part of the code is responsible for this case.

Thanks for reporting, @dfdx! A fix should be merged soon. Until then, you can just delete the semicolon after the oneof field definition.
