@title{SRFIs: Libraries}

The @link["http://srfi.schemers.org/"]{Scheme Requests for
Implementation} (a.k.a. @deftech{SRFI}) process allows individual
members of the Scheme community to propose libraries and extensions to
be supported by multiple Scheme implementations.

Racket is distributed with implementations of many SRFIs, most of
which can be implemented as libraries. To import the bindings of SRFI
@math{n}, use

@racketblock[
(require @#,elem{@racketidfont{srfi/}@math{n}})
]

This document lists the SRFIs that are supported by Racket and
provides a link to the original SRFI specification (which is also
distributed as part of Racket's documentation).

@srfi[1]{List Library}

This SRFI works with pairs and lists as in @racketmodname[racket],
which are immutable, so it does not export @racketidfont{set-car!} and
@racketidfont{set-cdr!}. The other provided bindings that end in
@racketidfont{!} are equivalent to the corresponding bindings without
@racketidfont{!}. Functions that are documented in the SRFI in bold
(but not bold italic) correspond to @racketmodname[racket] functions,
while the others are distinct from same-named @racketmodname[racket]
functions.

The date structure produced by this SRFI library is identical
to the one provided by @racketmodname[racket/base] in most cases
(see @racket[date]).

For backwards compatibility, when an invalid date field value is
provided to the SRFI constructor, the constructor will produce a lax
date structure. A lax date structure is @emph{not} compatible with
functions from @racketmodname[racket/base] or
@racketmodname[racket/date]. SRFI functions such as
@racket[string->date] may return a lax date structure depending on the
format string.

@(define srfi-19-eval (make-base-eval))
@(srfi-19-eval '(require srfi/19))

@defproc[(lax-date? [v any/c]) boolean?]{

Returns @racket[#t] if @racket[_v] is a lax date structure. Otherwise
returns @racket[#f].
