Will fix them right way!

World is a global name. There's no such thing as the current world for 
the whole image. There could be several worlds, or none. Additionally, 
globals are bad, and reducing them is good. And absolute reference 
systems re bad too. Relative references are much better.

Maybe you can use #world or #runningWorld. These are relative references 
(to some morph, or some process).
