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 by using a single
parameter, instantiated to a dictionary, and by defining a set of predicates
for accessing the individual parameters by a key (instead of using the
Logtalk built-in `parameter/2` method that indexes individual parameters by
position). The access predicates are goal-expanded to the corresponding
SWI-Prolog dictionary built-in predicates.
