Previously, some hacks were used to obtain the internal identifiers that implemented keyword functions directly, and give them types at startup. Now, the primary "function" (eg, `sort`) is given a type, and when used, the residual syntax properties are used to find `sort` from the real functions, and then the type of the real function is computed from the type of `sort`. Some creativity was required in the types of functions which take optional arguments that when present, alter the return type, such as `regexp-match*` and `file->list`. |

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.
