Re^3: Split a string based on change of character

I never thought of

grep $i=!$i,
[download]

before. I usually use

grep $i^=$i,
[download]

Yours is easier to understand, though.

Update: Yeah, I mean grep $i^=1,.

But `$i^=$i` makes $i 0 at once. So it's different to `$i=!$i` Back in the ancient times of C64 Basic I used `j=1-j` `s$$([},&%#}/&/]+}%&{});#$&&s&&$^X.($'^"%]=\&(\|?{%` `+`.+=%;.#_}\&"^"-+%*).}%:##%}={~=~:.")&e&&s""`$''`"e	[reply] [d/l] [select]

I think ikegami meant `$i^=1`, i.e.: `my @words = grep $i^=1, split /(?<=(.))(?!\1)/, $string;` [download] which does work.	[reply] [d/l] [select]
