That isn't the syntax for a loop local variable in Perl 6.
You are trying to use the Perl 5 syntax, which is not going to work in Perl 6
This is the Perl 5 code you are trying to write
while( my $f = readline $fh ){ say "$f\n"}
Which actually would turn into the following by Perl 5 compiler

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.

Is that true? I supposed that it would hold the Seq as a
This:
my $f = $fh.lines;
will slurp all the lines into $f (but you can still access the individual
items with something like $f[4]).
So you don't want to use this in a while loop, since everything will be
consumed during the first loop iteration. Either use a for loop to process
the lines one by o

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 having to d
