A sum type is defined as a choice between N type constructors, each having zero or more fields.ÄThe number of constructors becomes the dimensionality of the embedding space, and the constructor position (as defined in its implementation) is interpreted as the index of the nonzero coordinate.7NB : This function computes the generic representation only up to the  outermost" constructor (see examples below).3The type of the input value must be an instance of  (from GHC.Generics) and of  (from the `generics-sop` library).
