I used to think that until I tried rope in Emacs for editing 
Python code. After that I wanted proper refactorign for 
everything else as well. Renaming doesn't require checks, 
extracting a method is just easy... it's saved me a _lot_ of time 
and I just couldn't imagine having done some of the work I did 
without it.
