Freeing and Shuffling Namespaces


I have a standalone class.

class Foo

Now I wish to put this into another project,
which has a toplevel module namespace.


module Bla

I however had also want to call class Foo; end directly,
from the commandline as well, but also from other scripts,
without having to include Bla namespace.

In other words:

Is it possible to put a standalone class, like Foo,
into another module namespace, at runtime?

Bla.attach Foo

Or something like that?
