sometimes, especially when I'm trying to figure out something new, I like keeping the old exploratory code so I can grep through it or easily compare different approaches. It's less cognitive load than dealing with tags or branches or versions. usually I end up with old/try1 old/try2 ... old/tryn once I've worked out the way I really want to go, then I nuke old.
