ISupportsConstructorChain

[viluon]

An interface for method chaining of constructors. ISupportsConstructorChain would set the __call metamethod to the constructor of the implementing class, which would allow constructs like

local a, b, c = Point3D ( 1, 2, 3 ) ( 2, 3, 4 ) ( 3, 4, 5 )

Wait, brain fart! Simply setting __call to the constructor wouldn't work, since we need to return all 3 Point3Ds, not just the last one (referring to the example). We need to store the points that are being constructed in an array somewhere, and unpack them on every __call. That will give the result we wanted!
