== Basic libraries ==

1. What list library should R7RS-large provide?

 * No vote
 * None
 * [http://srfi.schemers.org/srfi-1/srfi-1.html SRFI 1] (passed)

2. What vector library should R7RS-large provide?

   SRFI 133 is a minor variant of SRFI 43 to make it compatible with R7RS-small by renaming a few procedures. It also includes a few additional procedures not present in SRFI 43.

 * No vote
 * None
 * [http://srfi.schemers.org/srfi-133/srfi-133.html SRFI 133] (passed)

3. What string library should R7RS-large provide?

   SRFI 13 is an index-based string library. SRFI 130 provides support for string cursors as well, but does not provide string mutation procedures. SRFI 135 is an immutable text library, but accepts strings as well; if you vote for it, you may want to vote "None" here.

 * No vote
 * None
 * [http://srfi.schemers.org/srfi-13/srfi-13.html SRFI 13]
 * [http://srfi.schemers.org/srfi-130/srfi-130.html SRFI 130]

No final result: this will be reballoted.

4. What sorting library should R7RS-large provide?

   SRFI 132 is an edited version of the withdrawn SRFI 32, with the algorithm-specific procedures removed and a few additional procedures; it provides sortedness testing, stable and unstable sorting, merging, duplicate removal, median, and selection. R6RS provides only stable sorting and merging.

 * No vote
 * None
 * [http://www.r6rs.org/final/html/r6rs-lib/r6rs-lib-Z-H-5.html#node_chap_4 R6RS]
 * [http://srfi.schemers.org/srfi-132/srfi-132.html SRFI 132] (passed)

== Sets and maps ==

5. What general set and bag library should R7RS-large provide?

   SRFI 113 provides linear-update sets and bags, which can be mutable or immutable according to the implementer's preference. Since the interface of SRFI 113 depends on SRFI 114, which has been replaced by SRFI 128, voting for SRFI 113 will cause your vote on comparator libraries to be automatically changed to SRFI 128.

 * No vote
 * None
 * [http://srfi.schemers.org/srfi-113/srfi-113.html SRFI 113] (passed)

6. What character set library should R7RS-large provide?

   SRFI 14 provides linear-update sets and bags, which can be mutable or immutable according to the implementer's preference. The contents are limited to characters.

 * No vote
 * None
 * [http://srfi.schemers.org/srfi-14/srfi-14.html SRFI 14] (passed)

7. What hash table library should R7RS-large provide?

   SRFI 69 is a basic hash table library. SRFI 125 is an upward compatible extension of it. Likewise, R6RS provides a basic hash table library, of which SRFI 126 is an upward compatible extension. Since the interface of SRFI 125 depends on SRFI 128, voting for SRFI 125 will cause your vote on comparator libraries to be automatically changed to SRFI 128.

 * No vote
 * None
 * [http://srfi.schemers.org/srfi-69/srfi-69.html SRFI 69]
 * [http://srfi.schemers.org/srfi-125/srfi-125.html SRFI 125] (passed)
 * [http://www.r6rs.org/final/html/r6rs-lib/r6rs-lib-Z-H-14.html#node_chap_13 R6RS]
 * [http://srfi.schemers.org/srfi-126/srfi-126.html SRFI 126]

== Immutability ==

8. What immutable pair/list library should R7RS-large provide?

   SRFI 116 is a variant of SRFI 1 for immutable pairs, which are a separate data type from ordinary Scheme pairs. Only a few functional update procedures are provided. Procedure names are prefixed with "i".

 * No vote
 * None
 * [http://srfi.schemers.org/srfi-116/srfi-116.html SRFI 116] (passed)

9. What random access pair/list library should R7RS-large provide?

   SRFI 101 is a library for purely functional pairs and lists with O(log n) access time. To avoid conflicts, procedure names will be prefixed with "r" for R7RS-large purposes.

 * No vote
 * None
 * [http://srfi.schemers.org/srfi-101/srfi-101.html SRFI 101] (passed)

10. What immutable deque library should R7RS-large provide?

   SRFI 134 is a library for immutable double-ended queues, with O(1) addition and removal time at both ends.

 * No vote
 * None
 * [http://srfi.schemers.org/srfi-134/srfi-134.html SRFI 134] (passed)

11. What immutable text library should R7RS-large provide?

   SRFI 135 is a library for immutable character sequences with O(1) access time. Its procedures accept strings as well as texts, so that a separate string library may not be as useful.

 * No vote
 * None
 * [http://srfi.schemers.org/srfi-135/srfi-135.html SRFI 135] (passed)
 * [http://srfi.schemers.org/srfi-140/srfi-140.html SRFI 140]

Laziness
12. What generator library should R7RS-large provide?

   SRFI 121 is a collection of routines for manipulating generators, which are nullary procedures that are invoked repeatedly to generate a sequence of values. They provide lightweight laziness.

 * No vote
 * None
 * [http://srfi.schemers.org/srfi-121/srfi-121.html SRFI 121] (passed)

13. What lazy sequence library should R7RS-large provide?

   SRFI 127 is a variant of SRFI 1 for lazy sequences, which are either proper lists or lists with a generator in the tail. They provide medium-weight laziness.

 * No vote
 * None
 * [http://srfi.schemers.org/srfi-127/srfi-127.html SRFI 127] (passed)

14. What stream library should R7RS-large provide?

   SRFI 41 provides classical streams based on delay/force. They provide heavyweight laziness.

 * No vote
 * None
 * [http://srfi.schemers.org/srfi-41/srfi-41.html SRFI 41] (passed)

== Miscellaneous ==

15. What box library should R7RS-large provide? *

   SRFI 111 is a trivial library for boxes (single-slot records).

 * No vote
 * None
 * [http://srfi.schemers.org/srfi-111/srfi-111.html SRFI 111] (passed)

16. What list queue library should R7RS-large provide?

   SRFI 117 provides mutable half-deques with O(1) addition at both ends and O(1) deletion from the front. They are based directly on ordinary Scheme lists, and are known in other Lisps as "tconc structures".

 * No vote
 * None
 * [http://srfi.schemers.org/srfi-117/srfi-117.html SRFI 117] (passed)

17. What ephemeron library should R7RS-large provide?

   SRFI 124 provides ephemerons compatible with MIT Scheme except that they are immutable. A dummy implementation for systems without GC support is also provided.

 * No vote
 * None
 * [http://srfi.schemers.org/srfi-124/srfi-124.html SRFI 124] (passed)

18. What titlecase library should R7RS-large provide?

   SRFI 129 is a modified version of R6RS titlecase support with full Unicode compatibility. It is less useful with SRFI 135, which provides titlecase support already.

 * No vote
 * None (passed)
 * [http://srfi.schemers.org/srfi-129/srfi-129.html SRFI 129]
