I don't like it, IMHO it's

  1. hard to read golfing!
  2. not DRY
  3. and furthermore buggy in edge cases.

you might get used to it, but the next one to maintain your code wont be "pleased".

Look! If you need it often, so why don't you just use your custom routine?

Just compare the overhead to document this hack with just encapsulating all the infos in a sub!

Or use something from List::MoreUtils ?

  DB<117> use List::MoreUtils qw/part/;

  DB<118> my $i; part {$i++ %3} a..h
 => (["a", "d", "g"], ["b", "e", "h"], ["c", "f"])

  DB<119> use feature 'state'; part {state $i++ %3} a..h
 => (["a", "d", "g"], ["b", "e", "h"], ["c", "f"])

update

oops sorry, this transposed the matrix, corrected code:

  DB<139> use feature "state";  part {state $i++/3} a..h
 => (["a", "b", "c"], ["d", "e", "f"], ["g", "h"])
