Can we get a clear statement about what a rewrite process would look like?
Can the new author read the old method? Can someone else produce a
requirements document that specifies what the method needs to do? Can
someone write tests from the old method that need to pass with the new
I still do not understand what we are allowed to do in order to reverse
engineer an unclean method.
