Final SRFI 224: Integer Mappings

Scheme Request for Implementation 224,
"Integer Mappings,"
by Wolfgang Corcoran-Mathe,
has gone into final status.

The document and an archive of the discussion are available at https://srfi.schemers.org/srfi-224/.

Here's the abstract:

Integer maps, or fxmappings, are finite sets, where each element is an association between a fixnum (exact integer) key and an arbitrary Scheme object. They are similar to the general mappings of SRFI 146, but the restricted key-type allows implementations of fxmappings to benefit from optimized structures and algorithms. This library provides a rich set of operations on fxmappings, including analogues of most of the forms provided by SRFI 146. Fxmappings have no intrinsic order, but may be treated as ordered sets, using the natural ordering on keys; a substantial sublibrary for working with fxmappings in this fashion is included.

Here is the commit summary since the most recent draft:

• Fix typo.
• Fix typo in example.
• copy edits
• Link to Wikipedia definition of trichotomy law.
• Don't use lower-case names at starts of sentences.
• Fix example. `srfi-alist' doesn't return two values.
• Wrap examples to avoid horizontal scrolling.
• Finalize.
