Shadowing core "I" is too messy. As soon as ed is loaded in memory, nothing else that isn't "i-aware" can be loaded anymore. I guess that's why "contexts" exist in Starting Forth, but adding this concept just for allowing the shadowing of core words seems overkill to me. Renaming I to i in ed seems better.
