Even if you weren’t concerned with backward compatibility, I still wouldn’t want to do it C-style, where “main” is a procedure which is given the command-line strings as arguments and is expected to return the exit status. Much better to access these via library routines (or implicit globals). Makes it easier to write separate argument-parsing code, that kind of thing.
