Example from Linguist:
% this is a Logtalk source file :- object(hello_world). % the initialization/1 directive argument is automatically executed % when the object is loaded into memory: :- initialization((nl, write('********** Hello World! **********'), nl)). :- end_object.
Example from Wikipedia:
?- my_first_object::p2. ERROR: error(permission_error(access, private_predicate, p2), my_first_object::p2, user)
