## self/1

#### Description

    self(Self)

Returns the object that has received the message under processing. This private method is translated to a unification between its argument and the corresponding implicit context argument in the predicate containing the call. This unification occurs at the clause head when the argument is not instantiated (the most common case).

#### Template and modes

    self(?object_identifier)

#### Errors

`(none)`

#### Examples

    test :-
        self(Self),                                   % after compilation, the write/1
        write('executing a method in behalf of '),    % call will be the first goal on
        writeq(Self), nl.                             % the clause body
