(this is similar to being flat, but struct contract (lazy ones) can be non-flat and still have no negative blame). Use this to optimize struct/dc contracts; specifically when a contract has no negative blame, then we don't need to add additional wrapping for indy-ness. This ended up being fairly tricky to handle the case where there are several mutually recursive define-opt/c functions. The code tracks which definitions depend on which ones and does a graph traversal of the dependencies to find if there is any non-negative blame possible. Naturally, this uses Racket's macro system to communicate between the definitions. |

The Racket programming language =============================== Important executables: * DrRacket: Racket's integrated development environment (start here!). * Racket: the main command-line entry point for running racket programs and scripts. * GRacket: the GUI-mode Racket executable. * raco: Racket's command-line toolset. More Information ---------------- Racket comes with extensive documentation: use DrRacket's `Help' menu, or run `raco docs'. Also, visit us at http://racket-lang.org/ for more Racket resources.
