     higher order functions, some useful control operators, and functions
     combining Lisp lists and Awk arrays such as `group_by`.

+Several unreleased headers are in the development queue:
+
+*   `<field.h>`: utilities for manipulating fields.
+
+*   `<varg.h>`: utilities for writing variadic functions in Awk;
+    the private API version of this is used in existing work, but does
+    not have separate test cases, and doesn't have a public, documented
+    version.
+
+*   `<array.h>`: some associative array utilities.
+
+*   `<alist.h>`: Lisp-like assoc lists: addendum to `<cons.h>`.
+
