4 R5RS Initialization Library🔗

 (require r5rs/init) package: r5rs-lib

The r5rs/init module re-exports r5rs, and also sets parameters as follows:

(read-case-sensitive #f)
(read-accept-infix-dot #f)
(read-curly-brace-as-paren #f)
(read-square-bracket-as-paren #f)
(print-mpair-curly-braces #f)

The side-effect of setting these parameters is useful when the module is required before loading an R5RS program, so that the reader and printer behave more as specified in R5RS. In particular, the plt-r5rs executable initializes by importing r5rs/init.
