![]() When recompiling from machine-independent form to an VM- and platform-specific form, cross-module inlining could fail due to an module path index being resolved in the wrong mode (loading versus non-loading). As a concrete example, "racket/draw/private/bitmap.rkt" tended to be recompiled in a way that did not inline `_ubyte` as `_uint8`, which in turn made `ptr-set!` and `ptr-ref` operations much slower, which would make certain bitmap operations drastically slower.

Racket is a general-purpose programming language and an ecosystem for language-oriented programming.
This repository holds the source code for the core of Racket plus some related packages. The rest of the Racket distribution source code is in other repositories, mostly under the Racket GitHub organization.
Quick Start
Pre-built versions of Racket for a variety of operating systems and architectures, as well as convenient source distributions are available at
https://download.racket-lang.org
Racket comes with extensive documentation, including several tutorials. You can read all of this documentation, as well as documentation for third-party packages at
