Of course, I am always happy to give credit where credit is due :)

Having Moosified several older code bases, I have found that  
incremental conversion tends to work to a point. At some point you  
have to untangle some of the knots that vanilla Perl OOP sometimes  
puts you in, and they tend to not map directly to Moose-isms as well.  
I had this issue with my IOC module, and ended up just re-writing it  
from scratch as Bread::Board.
