In particular, instead of trying to collect all of the arrows and do some kind of a smart transitive closure (that tries to avoid adding links that would "skip" expressions but doesn't always manage it), the new code tries instead to build the right links directly while traversing the fully expanded expression This also seems to have been a minor performance improvement. When running the information collection phase of check syntax (ie, not counting the time for expansion) on a 1.8 GHz core i7, for collects/framework/private/text.rkt, the times went from: cpu time: 7347 real time: 7413 gc time: 211 cpu time: 7328 real time: 7393 gc time: 239 cpu time: 7356 real time: 7418 gc time: 240 to: cpu time: 7562 real time: 7632 gc time: 265 cpu time: 7555 real time: 7618 gc time: 269 cpu time: 7552 real time: 7617 gc time: 262 closes PR 11835 do not include in 5.2 |

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.
