No it isn't true.
It stores the Seq in $f.

The following doesn't print anything.

    my $f = 'example.txt'.IO.lines.map(*.say); Nil

(Note that I added `Nil` so that if someone tried this in the REPL, it
doesn't try to `say` what's in `$f`.)

What it does do is make the Seq marked as an item, so this only runs
one loop, and doesn't run the `.map` code.

    for $f { Nil }

But both of these will:

    for @$f { Nil }
    for $f<> { Nil }
