Subject: Re: strange behavior

I think the problem here may be how "include" works. 

In this example, at runtime, A.constants   => ['CC', 'AA']

In module B, AA is accessible but CC is not.   

"include", which appends features at
runtime, is expected (from me) to make the included module function
and constants  a part of the calling module, that is, at runtime, 
a copy and paste operation. What would you see as advantage for 
the current "include" behavior over the above said one.

Thanks
