case class TorsoForm(torso: Term, apps: List[Appendage]) extends HashEquality[TorsoForm] with Product with Serializable

The torso form of a term is named akin to the head normal forms.

For example, OMA(h1, OMA(h2, tr, ext2), ext1) is in torso form with tr as the torso and (h1,ext1) and (h2,ext2) as Appendages that are attached to the torso.

Its torso normal form is TorsoNormalForm(c, Appendage(h1, ext1) :: Appendage(h2, ext2) :: Nil)

The point of the torso normal form is understood by considering a type theory, whose constructor are paired into introduction and elimination operators. Then the torso form is a useful representation for a series h1, h2, ... of eliminators applied to a term (the torso). The torso is either atomic or a sequence of introductors. In the latter case, a reduction rule (e.g., beta) can be applied, which eventually yields an atomic torso.

For example, OMA(@,OMA(pi1,c),a) arises from the constant c (of product type) by first projection out a component (a function) and then applying it to a.
