    The various representations of an arbitrary query, as seen by the filesystem connectors, along with the operations for dealing with them.

    There are a few patterns that are worth noting: - (src: A, ..., lBranch: FreeQS[T], rBranch: FreeQS[T], ...) – used in operations that combine multiple data sources (notably joins and unions). This holds the divergent parts of the data sources in the branches, with SrcHole indicating a reference back to the common src of the two branches. There is not required to be a SrcHole. - Free[F, A] – we use this structure as a restricted form of variable binding, where F is some pattern functor, and A is some enumeration that has a specific referent. E.g., FreeMap is a recursive structure of MapFunc that has a single “variable”, SrcHole, which (usually) refers to the src parameter of that operation. JoinFunc, FreeQS, and the repair parameter to Reduce behave similarly. - We use the type parameter QS[_] to indicate QScript, as well as the type parameters IN[_] and OUT[_] to indicate the input and output coproducts in transformations where they can be different.
