Subject: Re: Dynamic class names

No... I mean the 'Name' of a class or module (that what you get with 
object.class.name). The doc of Class::new (ri) describes how it works:

> You can give a class a name by assigning the class object to a constant.

...but still that doesn't allow me to set the initial name when _defining_ the 
class.

I am aware that this can be done using eval with the complete class definition 
as a string - which is also not what I want.

The reason is to avoid name clashes of a larger program. So I am thinking of 
using some central instance to assign names and address specific types of 
classes.
