 Inheritance Implementation Strategies 

So how to implement the big three via concatenation inheritance?

For simplicity, let's assume a sequential search of the environment table when trying to resolve a variable.

Will use Sway syntax from here on out.

The quintessential class/constructor:

function node(item,next) {       this; }

Making nodes:

var items = node(1,node(2,node(3,:null)));

Or shorthand: var # = node; var items = right(1 # 2 # 3 # :null);

Using nodes:

while (items != :null) {       inspect(items . item); items = items. next; }

The function right can be written in Sway using reflection.
