Reification Inheritance
Reification inheritance: whereby the subclass completes (or partially completes) an incomplete superclass.
function super() { function a(x) { b(x * x); } this; }
function sub() { function b(y) { y + 1 * (y - 1); } extends(super()); }
Now we make a sub object:
var s = sub(); inspect(s . a(3));
The output is:
s . a(3) is 80
Sway allows you to look at the concatenated environment:
ppObject(s);
yields:
<OBJECT 5651>: context: <OBJECT 654> dynamicContext: <OBJECT 654> callDepth: 1 constructor: <function sub()> this: <OBJECT 5651> b: <function b(y)> a: <function a(x)>
