SPUG: Change a namespace after loading?

[Bill Warner]

Hi all,

I want to change the namespace of a class after it's been loaded. Worse, I 
want to continue to use the original namespace, but fill it
with new code that might refer to the old code in the changed namespace. 
Wore still, I'd rather not edit the old code at all. I want to
import it as I've always done, but into a new namespace.

Is there technique or a module for this purpose?

Thanks,

  -Bill
