Yep, and it could probably be coded up in a page of Perl.
Problem is, introducing changes (whether manually or via
programs) always carries some risk. How sure am I that:
* the new syntax will be functionally equivalent
in all possible cases (including buggy code that
currently works only by happenstance :-)
* the program won't foul up the editing process,
putting arrows in places where they don't belong
* "use script" will catch anything that's worng
If I'm not _entirely_ sure of these, the conservative
approach is to do minimal changes.
