      Use a named representation of binding in heap_lang. · eba4ac6e
      Robbert Krebbers authored
      We can use a named representation because we only substitute closed values. This
      idea is borrowed from Pierce's Software Foundations.
      
      The named representation has the following advantages:
      * Programs are much better readable than those using De Bruijn indexes.
      * Substitutions on closed terms (where all variables are explicit strings) can
        be performed by a mere simpl instead of Autosubst's asimpl. The performance
        of simpl seems better than asimpl.
      * Syntactic sugar refolds better.
