If you want to read you lines in groups of 3 then you want batch : for @x.lines.batch(3) -> @b
If you just want the third line and throw away the first I'd probably do a tail on that. for @x.lines.batch(3).map( *.tail ) -> $l Note you need to map the tail on each batch of three not slap it on the end.
