   1 \section{Evaluation}
   2 All in all we are quite happy with \SPLC{}. Our added syntactic sugar and the
   3 higher order functions make our implementation of \SPL{} quite comfortable to
   4 program in. Due to the UNIX style interface it is quite easy to combine
   5 usage of the compiler with \SSM{}.

   7 There are however of course a lot of things to can be improved. We discuss
   8 a few of
   9 the most interesting and most pressing issues. First of all error handling in
  10 \SPLC{} can be greatly improved. Currently a lot of error happen at position
  11 (0,0), most notably all type errors happen at this position. It would be a great
  12 improvement in usability if errors would always be reported at the correct
  13 position. A second issue is that in \SPLC{} it is not possible to spread a
  14 program over multiple modules, when developing larger programs this would an
  15 absolute requirement. Thirdly \SPLC{} currently does not allow for multiple
  16 recursion, and all functions need to be declared before they are called. It
  17 would be nice to have multiple recursion and to not be forced to structure your
  18 program in the order in which functions are called.
