To convert a program from dynamic binding to lexical binding is not a trivial transformatoin -- it requires actually understanding the code. It would be bad judgment to require people to do that work for their old programs merely to simplify one small piece of the language. -- Dr Richard Stallman (https://stallman.org) Chief GNUisance of the GNU Project (https://gnu.org) Founder, Free Software Foundation (https://fsf.org) Internet Hall-of-Famer (https://internethalloffame.org)
