>> implementation

Hi,

I was reading code when I find several implementation of #>> selector.
But they all have the same body. (Except for Integer).

So why?

Hi Math,

You have perhaps seen that in a recent 3.9 image?

You can switch on the preference to show annotation panes in browsers,  
then you'd see that the methods (except for CArray and Integer) are indeed  
the same code+version: there's only one #>> method "propagated" by the  
traits system.

Hope that helps.

Traits are a very interesting way of writing softwares. You can write
behavior in something that look like a class without state (namely a
trait) and use this behavior in the classes you want.

I recommend you to read 'Traits, composable units of behavior' which is
short and clear. I found this article very interesting.
