As someone who has done quite a bit of "grep based refactoring", one
observation: of course, this can only me made semi-manually. But then,
the process has found things for me a syntax based refactoring tool
wouldn't ever have, like a variable name's mention in a comment (or
docstring, or even more insidious: possibly temporarily un-commented
code!) where I went "oh, yes, I want to change that too".

Food for thought.

Cheers
