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 ;-) Cheers Rolf _{(addicted to the Perl Programming Language :) Wikisyntax for the Monastery}	[reply] [d/l]

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;` [download] And I agree that once you have learned about `\K` and `/r` you will you that over and over and over again. Enjoy, Have FUN! H.Merijn	[reply] [d/l] [select]
