Yes, the default is a real assignment even if it is conditional.

A keyword isn't an assignment, it is a labeling specification.  To be most
exact it is a key,value pair like in a dictionary construction, so
technically it should be a colon, not an equals sign.

    func(y: 1, z: 2, x: y := 3)

We can discuss this further if the vote goes through.
