This folder contains several examples of using Prolog built-in meta-predicates and module meta-predicates that take closures as arguments. It is used to help test the Logtalk support for dealing with closures as it requires generation of a helper predicate per call to workaround a clash between the way Logtalk compiles predicates and the way a closure is extended to form a goal.

This example supports using ECLiPSe, GNU Prolog, SICStus Prolog, SWI-Prolog, Trella Prolog, and YAP as the backend compilers.
