Matthew Flatt bff31f0768 expander: allow syntax-local-lift-require during #%module-begin expansion 
Making `syntax-local-lift-require` during `#%module-begin` expansion
provides a solution to a long-standing problem with composing
languages via `#%module-begin`, where the bindings of some lanuage
should be made available for expanding the module body by
`#%module-begin` expansion (i.e., the language is *not* the initial
import). If the language does not support `require`, then there was no
way to expand and expose the language import dependency.

Closes #1352

README.md

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

https://docs.racket-lang.org
