G'day mikkoi,

[Disclaimer: I'm not a Dancer2 user; in fact, I needed to install it for the tests below. I just used available documentation for the code I wrote.]

Dancer2::Core::Role::ConfigReader has:

"... provides a setting() method which is supposed to be used by externals to read/write config entries."

Running this (quick-and-dirty) script: 

#!/usr/bin/env perl

use strict;
use warnings;

use Dancer2;

get '/hello' => sub {
    return 'Hello, world!';
};

get '/my_stuff' => sub {
    my $my_stuff = setting('my_stuff') || {};
    my $x = $my_stuff->{X} || 'not set';
    my $y = $my_stuff->{Y} || 'not set';
    return "X[$x] Y[$y]";
};

get '/my_new_stuff' => sub {
    setting('my_stuff' => {X => 'newX', Y => 'newY'});
    return 'New stuff configured.';
};

dance;

I was able to do: 

$ curl http://localhost:3000/hello
Hello, world!

$ curl http://localhost:3000/my_stuff
X[not set] Y[not set]

$ curl http://localhost:3000/my_new_stuff
New stuff configured.

$ curl http://localhost:3000/my_stuff
X[newX] Y[newY]

That seems to be the type of thing you're trying to do. Apologies in advance if I'm barking up the wrong tree.
