|apply_macros.pl -- Goal expansion rules to avoid meta-calling|
This module defines goal_expansion/2 rules to deal with commonly used, but fundamentally slow meta-predicates. Notable maplist/2... defines a useful set of predicates, but its execution is considerable slower than a traditional Prolog loop. Using this library calls to maplist/2... are translated into an call to a generated auxiliary predicate that is compiled using compile_aux_clauses/1. Currently this module supports:
The idea for this library originates from ECLiPSe and came to SWI-Prolog through YAP.
