[sc34wg3] New syntax for (binary) associations

[Lars Heuer]

Hi Dmitry,

[...]

[...]

But how is that different from defining a template (in the CTM
context)?

    def works-for($employee, $employer)
        o:works-for(o:Employee: $employee, o:Employer: $employer)
    end

    def has-employee($employer, $employee)
        works-for($employee, $employer) # Calling the "works-for"
                                        # template with flipped vars
    end

    john works-for(o:TheDreamWorldInc).

    o:TheDreamWorldInc has-employee(john).


Best regards,
Lars
