The problem is is that you aren't really relearnig anything. C-script and Lite-C are remarkably similar. The changes you'd have to make are minor and conversion is well documented. There are a couple of sections where it gets into new territory, but all and all it's not a huge difference. It's just a lot of little things that just happen to add up; however once you've used the new way a few times, it will become 2nd nature just like anything else.
