This looks great! Will use for v2 and mark you as a coauthor, thank you :D
(let me know if there's a better way to do that also, still learning the process)

I wasn't sure what `$.` was before but this makes it clear that it's the current

`$ARGV` is the name of the current file. (different from @ARGV)
