* @defgroup maplist Map List and Term Operations
* @ingroup library
*
* This library provides a set of utilities for applying a predicate to
* all elements of a list. They allow one to easily perform the most common do-loop constructs in Prolog.
* To avoid performance degradation, each call creates an
* equivalent Prolog program, without meta-calls, which is executed by
* the Prolog engine instead. The library was based on code
* by Joachim Schimpf and on code from SWI-Prolog, and it is also inspired by the GHC
* libraries.
*
* The following routines are available once included with the
* `use_module(library(apply_macros))` command.
