Subject: Re: Module inclusion at runtime...

I read you post several times over but I'm still not sure, whether I got
it completely.

You can't. It's locigally impossible since XYZ is part of Monday.
Everybody who wants to use XYZ must know about Monday.

Apart from that, nesting XZY twice into Monday (once directly and then via
Monday) is at least odd.  Maybe you let us know what you are trying to
accomplish and then somebody can come up with a more appropriate solution.

For this maybe something like this works, although I don't really like it:

a = aModule.name.split('::')
a.pop
parentName = a.join('::')
