Well, in JavaScript you can always Object.create(Point.prototype, ...).
In Java, for example, the ability to have multiple constructors can be very
convenient for that type of use case; but it always can be replaced with
factory methods and a private constructor with more parameters.
Actually, my original remark may be off-base anyway; I haven't followed the
discussion well enough. If the ".{" syntax returns a new object rather than
mutating one, then I was confused.
