Actually, setting $/ to '' puts Perl into paragraph mode, with blank lines
(i.e. consecutive newlines) as the input separator.

To ignore newlines completely, you need to set $/ to undef, either with:

$/ = undef;

or:

undef $/;

or, preferable:

local $/;

which will restore $/ back to its previous value at the end of the block.

I think you're right about that.
