+      \item New class \code{StretchyList} for pair lists with fast addition of
+      elements at the front and back. This abstracts the 3 functions
+      \code{NewList}, \code{GrowList} and \code{Insert} used in various 
+      packages and in parsers in R.

       functions were incorrectly expanding to the no-degree-of-freedoms
       variant.
