Matthew Flatt 75ba7ff5bc cptypes: discard call form around an error, better cm support
An an example of better error handling,

 (f (error 'x "x") y x)

turns into

 (error 'x "x")

which may allow further propagation through `begin` and `if` as
alerady implemented.

Also, make cp0 and cptypes more aware of
`call-{setting,getting,cosuming}-continuation-attachment` in terms of
result types and single-valuedness. The single-valued part requires
some generalization to the existing `single-valued?` support (by
default, "single-valued" => "doesn't inspect/changed immediate mark")
in both cp0 and cptypes.

Finally, the "optimize.rktl" test suite is now enabled for Racket CS.
The tests helped expose some missed opportunities and bugs, and it
should be particularly helpful going forward, since we're back to
having a place for Racket-level optimization tests. Not all tests
written for BC pass with CS. Grep for 'chez-scheme for missed
optimization opportunities.

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

Building from Source
