A Comp is a composition operator: either a sequence, an option list, a parallel split, or a restriction operator. A top-level Comp is a call definition. Lower-level Comps you can think of as call "comp"onents.

Visitor pattern implementation for transformations. Each AstNode accepts a TransformVisitor and a value, and returns an instance of its own type (ie, Seq.accept(tv, "A") returns a Seq). The 't' parameter is a closure.
