Previously, to use these keywords in Robot Framework, you would have to do
this:

    ${animal}=    New animal    beef
    ${food}=      Get favourite food
    Feed          ${food}       ${animal}

After the aforementioned modifications, these keywords can be used in the
following way:

    New animal    beef                    Lion
    ${food}=      Get favourite food      Lion
    Feed          ${food}                 Lion
