Replace the response event with an arrayref. The first item in the
arrayref should be the response event; the remaining items are "magic
cookie" or other context data you send through the component.
>From the SYNOPSIS:
use POE::Component::Client::Ping ':const';
# post an array ref as the callback to get data back to you
$kernel->post('pinger', 'ping', [ 'pong', @user_data ]);
# use the REQ_USER_ARGS constant to get to your data
sub got_pong {
my ($request, $response) = @_;
my @user_data = @{$reqest}[REQ_USER_ARGS..$#{$request}];
}
The feature isn't documented in the DESCRIPTION. I'll fix that.
