in thread Yet Another Rosetta Code Problem (Perl, Ruby, Python, Haskell, ...)
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.
