( #3333=superdoc: print w/replies, xml ) Need Help??

You don't tell us what the argument to your handler subroutine is, although it is evidently an object of some type, as you call a print method on it. Since we do not know what $r is, we can only guess what arguments its print method accepts.

Your code:

$r->print({ 'response' => {'result' => $results,}, });

calls print with a an anonymous hash reference as the sole argument, which appears to have been stringified by that method, and you indicate that is not what you want. Perl does not actually allow hashes to be directly passed as arguments to subroutines: you can either pass a reference to a hash (which didn't have the behaviour you wanted in this case) or provide a list of alternating key/value pairs, which can be turned into a hash by the subroutine (if it is written that way). The latter would look like this:

$r->print(response => {result => $results});

Whether this works for you depends on what exactly the object $r is.

    [Corion]: Hi choroba, Discipulus!
    [Corion]: Yesterday I've been mulling over how to best generate HTTP requests from permutations of values but I haven't found a nice API for passing in the "template" of the HTTP request yet. I guess I'll have to do a SoPW for that
    [Corion]: The API itself will basically be my $iter = generate_http_requ ests(method => 'GET', url => '/settings/:name', headers => ???, get_params => ['foo','bar']), but I'm not sure how to parametrize values in the headers and how to specify lists of ...
    [choroba]: On the other hand, lots of options to receive the requests :-)
    [Corion]: ... values to be used. For example, I think for headers, one would want to have various kinds of Content-Encoding headers, but for the get_parameters one would have various kinds of Bobby Tables
    [choroba]: What about [metadoc:// Algorithm::Loops]?
    [Corion]: choroba: Yeah, but handing off the request to Dancer,Plack, Mojolicious,LWP is easy once I have the data filled into some structure ;))
    [choroba]: Algorithm::Loops
    [Corion]: choroba: I'm using that to generate the permutations, but I don't know how the user can pass the intended values to my function in a sane way
    [Corion]: I have a prototype that permutes the get_parameters, but the values used for the get parameters should be different from the values used for the headers and potentially for parts of the URL
