         AD in Fortran, Part 1: Design (2012), http://arxiv.org/abs/1203.1448). These extensions integrate
         forward and reverse AD directly into the programming model, with attendant benefits to flexibility,
         modularity, and ease of use. The implementation we describe is a
         “prepreprocessor” that generates input to existing Fortran-based AD tools. In
         essence, blocks of code which are targeted for AD by Farfel constructs are put into subprograms
         which capture their lexical variable context, and these are closure-converted into top-level
         subprograms and specialized to eliminate arguments, rendering them amenable to existing AD
         preprocessors, which are then invoked, possibly repeatedly if the AD is nested.",
