Yes, renaming is not very representative of "refactoring", which 
generally is intended to mean more complex reorganizations. 
(That's why I asked Walter if he considered renaming something to 
be refactoring, before arguing my point). Still, it seems 
reasonable to me to include renaming as part of the refactoring 
tools, conceptually and practically.

I chose the trivial task of renaming for the example because it 
was something everybody does, is easily understandable and 
adequate to the argument: a human and a generic editor 
function/macro do not do it as quickly and safely as a 
specialized refactoring tool which understands the language 
(which will fix all static uses of the old name, and can point 
out other places for review).
