Language::Prolog::Types::overload - nice formating for Prolog terms.
use Language::Prolog::Types::overload;
This module activates overloading features for Prolog terms.
When this module is loaded, Prolog terms are automatically converted to strings when printed or concatenated.
When used in bool context, all terms but variables return true, even the nil term.
In numerical context, functors return its arity and lists its length.
None by default.
