EDIT: I'm an idiot and as the other reply here shows, HTTP::Message already has this functionality built-in. ->add_part() is your friend. I should have looked a bit harder.

OK, so what you're looking for I haven't yet found on the CPAN. This is _completely_ untested, so please take it with a grain of salt (or 100 such grains).

You can create multiple HTTP::Request objects (get, post, etc). You can then group them all together in one new HTTP::Request object with a fairly simple function like I'm showing below and then just send that request:

use UUID qw(uuid);
use HTTP::Request ();
use Encode ();

sub build_multi {
    my ($method, $uri, $header, @requests) = @_;
    my $r = HTTP::Request->new($method, $uri, $header);

    my $boundary = uuid();
    $r->header(
        'Content-Type' => "multipart/mixed; boundary=$boundary"
    );

    my $content = '';
    for my $req (@requests) {
        $content .= $r->as_string("\015\012");
        $content .= "\015\012--{$boundary}";
    }
    $content .= '--' if $content;
    $r->content( Encode::encode_utf8($content) );
    return $r
}
