### 18.1 Revised7 Report on the Algorithmic Language Scheme

Description The core standard for the Scheme language. URL https://small.r7rs.org/attachment/r7rs.pdf Support Fully supported, with exceptions: `syntax-rules` doesn’t handle additional patterns after a segment pattern. This means that `(syntax-rules () ((a b ... c) …))` doesn’t work, even though `(syntax-rules () ((a b ...) …))` does work. `syntax-rules` doesn’t handle vector patterns or templates. Multiple values aren’t supported correctly. Instead `values` returns a special record containing the values, and `call-with-values` takes that record apart and passes the values to the receiver. For many uses of multiple values this is adequate. Libraries `(scheme base)` `(scheme case-lambda)` `(scheme char)` `(scheme complex)` `(scheme cxr)` `(scheme eval)` `(scheme file)` `(scheme inexact)` `(scheme lazy)` `(scheme load)` `(scheme process-context)` `(scheme r5rs)` `(scheme read)` `(scheme repl)` `(scheme time)` `(scheme write)` Global All names are bound in the MIT/GNU Scheme global environment.
