Closures as Modules?

Show all headers | View raw

Can anyone shed some light on this?

https://github.com/LouHenryAlvarez/jackbox

It looks like some sort of abstraction.  But I a having trouble understanding how this works.  Also the following code doesn't make any sense to me.

<pre>

Furhtermore, these decorators can be re-applied multiple times to the same receiver:

cup = Coffee.new.enrich(milk).enrich(sprinkles).enrich(sprinkles)
# or even..
cup = Coffee.new.enrich milk, sprinkles, sprinkles

cup.cost.should == 2.10
cup.should be_instance_of(Coffee)
cup.injectors.should == [:milk, :sprinkles, :sprinkles

</pre>

Isn't this sort of thing already possible already.  Can someone explain?


Thanks,

Kike
