in reply to Advantages to passing a hash to a subroutine?

The reasons behind why to use a hash of named arguments as a subroutine parameter is discussed in Perl Best Practices, Chapter 9, "Use a hash of named arguments for any subroutine that has more than three parameters". Luckily, Chapter 9 happens to be the free sample chapter from this book.

    Yes, thanks for pointing out the free PDF. Perfect!

    In Perl Best Practices, they state using "Named arguments replace the need to remember any ordering..Especially if you have, or are likely to have more than three arguments."
