The (r6rs)library is a composite of most of the libraries described in this report. The only exceptions are:
(r6rs records explicit) (section 5.2)
(r6rs mutable-pairs) (chapter 16)
(r6rs eval) (chapter 15)
(r6rs r5rs) (chapter 17)
The library exports all procedures and syntactic forms provided by the component libraries.
Note: Even though (r6rs records explicit) is not included, (r6rs records implicit) is included, which subsumes the functionality of (r6rs records explicit).
All of the bindings exported by (r6rs) are exported for both run and expand; see report section on “Import and export levels”.
