print $l;
}

I am curious as to what reasons there are for doing this, because there
does not appear to be any mention of it anywhere within the book.

Of ocurse I don't know what the author was thinking. But _I_ would write
this as
for my $| (0..9) {
print $|;
}

I hope not.


Another question is why he would possibly want to assign 0 to 9 to the
autoflush variable.

A third question is why you use a font which apparently uses the same
glyph for the pipe symbol and the lower case ell.
