But that code actually works. It returns the expected results, including the terminal email address. It just doesn't on hackerrank.com. It did when I changed [^\w\.] to (?:$|[^\w\.]), which is what the regex site needed.

If it's not a Perl version thing, then it's likely some kind of emulator issue on their part, or perhaps the regex web site is wrong in not matching it. It seems to me that EOD is not a word, personally.
