iterates the Seq, printing all the lines. The second call to .lines() returns nothing because you're now at eof, no more lines. Note the Seq that .lines returns itself is lazy.  It doesn't (necessarily) have all the lines, just the capability to get them. As you iterate the Seq, it pulls in all t

Yes, you're right, it is a Seq. I was trying to be pedagogical, but probably wasn't very accurate. It is a Seq, and the "slurping" will be lazy. Le mar. 9 oct. 2018 à 15:30, Curt Tilmes a écrit : > On Tue, Oct 9, 2018 at 9:27 AM Laurent Rosenfeld via perl6-users < > perl6-users@perl.org>

es. The second call to .lines() returns nothing because you're now at eof, no more lines. Note the Seq that .lines returns itself is lazy. It doesn't (necessarily) have all the lines, just the capability to get them. As you iterate the Seq, it pulls in all the lines. Curt

The eof method of the IO::Handle class returns True if you exhausted the contents of the handle, but you generally don't need to use that, since something like: for 'input.txt'.IO.lines -> $line { # Do something with $line } will gracefully handle ends of files for you without you hav
