Stringify 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.

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.

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.

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 wit
