No, it's not. The output even shows it is not.

("given ZBBBCZZ got", "Z", "BBB", "C", "ZZ")

Oh lord .... you are right!

All praise the /r flag! :)

And let's hope no one will ever stumble over the semipredicate whitespace you inject for splitting ;-)

[Tux]

Instead of using a space, I'd use U+002063. It would work just as the name suggests: INVISIBLE SEPARATOR

my @list = split m/\x{2063}/ => s{(.)\K(?!\1)}{\x{2063}}gr;

And I agree that once you have learned about \K and /r you will you that over and over and over again.
