This breaks old patches that rely on cyclone's [pow~].  This is a  
problem that many people have addressed in languages like python,  
java, ruby, etc.  The solutions generally look very similar, from what  
I have seen, so I think we should learn from their experience.

The last major piece of the puzzle is making loaded binary objectclass  
names be in the canvas-local namespace, just like abstractions are  
now.  Unfortunately, that's not so easy to write.  But I think its the  
right thing to do.

realize his wishes.  Now that he can realize them, he must either  
change them, or perish.    -William Carlos Williams
