Subject: [ruby-talk:26620] Re: Selector Namespaces: A Standard Feature for Smalltalk?

Ok. So if I understand this correctly, selector namespaces mean that:

We can add or modify a method in an existing class but have the change affect only selected parts of the system - because a given method can have several implementations that co-exist simultaneously and get  used in different parts of the system.  Thus: " '50' asMoney"  could cause the execution of different implementations of #asMoney, depending on where the method call appears.

I believe this has been a feature of  VisualAge Smalltalk for a long time already ("Extended classes").  Right ? Making it standard would be cool naturally, if it can be done simply.
