Convert the context's goal type into the HhGoal
type that the SLG solver understands. The expectation is that the context's goal type has the same set of variants, but with different names and a different setup. If you inspect HhGoal
, you will see that this is a "shallow" or "lazy" conversion -- that is, we convert the outermost goal into an HhGoal
, but the goals contained within are left as context goals. Read more
