== WG2 Input Docket ==

This docket contains work items that need to be voted on for possible inclusion into R7RS-large.  See [wiki:WG2Dockets WG2Dockets] for other dockets.

`cond` `=>` with guard as well as generator (see #89):  [http://srfi.schemers.org/srfi-61/srfi-61.html SRFI 61]

`cond` `=>` passes multiple values from predicate to consumer:

Custom I/O ports: [http://www.r6rs.org/final/html/r6rs-lib/r6rs-lib-Z-H-9.html R6RS]

Default exception handler controls:

Evaluator arguments to procedures like `load`: see #277

Extended exact numbers:  ExtendedRationalsCowan

External representation of records: 

Features, allowing libraries to add:

Identifier-syntax: [http://www.r6rs.org/final/html/r6rs/r6rs-Z-H-14.html#node_sec_11.19 R6RS]

`if` with arbitrarily many arguments: [http://dpk.io/r7rs/naryif-20130406 David Kendal's rationale]

R6RS versions of `real?`, `rational?`, `integer?`: these are false if the imaginary part is an inexact zero; the issue here is what to name them to avoid confusion

Immutable data: ImmutableData

Interrupts, timers, signals: 

Jiffy cleanup: [http://arcanesentiment.blogspot.com/2012/07/current-jiffy-is-not-usable-portably.html Arcane Sentiment blog post]

Macro expander(s) available at run time: 

Multiple values passed through => in `cond`: see #90 

`number->string` variant with control for significant digits: [http://lists.scheme-reports.org/pipermail/scheme-reports/2011-May/000709.html Vincent Manis proposal], R6RS

`number->string` and `string->number` with non-ASCII decimal digits: NumberStringUnicode

Observable objects: 

Port type detector: see #177

R6RS compatibility: whole libraries or cherry-picked procedures:

Raw strings:  <<, """...""", [http://srfi.schemers.org/srfi-109/srfi-109.html SRFI 109]

Record external representations: 

`standard-*-port` routines:  [http://www.r6rs.org/final/html/r6rs-lib/r6rs-lib-Z-H-9.html R6RS]

String positions and slices: [http://www.r6rs.org/formal-comments/comment-235.txt R6RS formal comment]

Tree library: at least `tree=?` and `tree-copy`, probably Common Lisp [http://www.lispworks.com/documentation/lw50/CLHS/Body/f_sublis.htm SUBLIS and NSUBLIS], fold, unfold, map ... 

Thread-local storage: 

Undefined value API: see #49

Unquote with multiple arguments:  see #123
