To load this example and for sample queries, please see the `SCRIPT.txt`
file.

This example requires using SWI-Prolog 7.x as the backend Prolog compiler.
It illustrates using a SWI-Prolog native dictionary term for representing
a parametric object parameters. This is accomplished simply by passing a
dict as the single object parameter.

Know issue
----------

Don't use dot notation, `./2`, when working with dicts within objects and
categories. SWI-Prolog provides different semantics for compiled versus
asserted clauses that contain `./2` terms and that can clash with Logtalk
dynamic binding caching and inlining optimizations (usually resulting
in instantiation errors).
