an argument to what sub?
(it's obvious that i've missed the boat on this concept)
my $writer = shift->(

The array @_ contains a sub ref as its first argument. It is this sub
that gets [ 200, [ "Content-type" => "text/plain" ], $s ] as its argument.
It can be rewritten as:
my sub_ref = shift @_;
my $writer = $sub_ref->(
[ 200, [ "Content-type" => "text/plain" ], $s ]
);

Confusion is the first step of understanding.
Programming is as much about organization and communication
as it is about coding.
The secret to great software: Fail early & often.
