Any

StageResult indicating that the stage emits/accepts an object of a arbitrary type.

Note that other stage result types cannot be implicitly converted into this type. A stage which performs type conversion (such as dev.ust.zinc.grader.pipeline.local.Barrier) is needed to convert this type from/to other result types.

This stage result type is a can of worms. Do not use this unless you know what you are doing, and prefer to add a new StageResult type instead of using this type.
