Big doubts about Stash Bundle

Question

I try to understand better Stash Bundles, so I tried to use Stash code to save a group of variables as a single variable in a defined bundle.

The variables:

{exp:stash:set_value name="un" bundle="default"}
{exp:stash:set_value name="deux" bundle="default"}
{exp:stash:set_value name="trois" bundle="default"}

The group of the variables inside a defined bundle:

{exp:stash:bundle name="bundle"}
        {exp:stash:get  name="un"}
        {exp:stash:get  name="deux"}
        {exp:stash:get  name="trois"}
{/exp:stash:bundle}

Call the defined bundle

{exp:stash:get name="bundle"}

Results (in the html page):

a:3:{s:2:"un";N;s:4:"deux";N;s:5:"trois";N;}

Why the variables appears like this, and not display:

un
deux
trois

What it means a:3:{s:2: ;N; ? I'm totally lost. How to display only un deux trois?

Thanks.

Additional information.

I tried with:

http://site/stash/bundles

    {exp:stash:bundle name="segments"}
            {exp:stash:get name="{segment_1}"}
            {exp:stash:get name="{segment_2}"}
    {/exp:stash:bundle}

   <h1>{exp:stash:get name="segments"}</h1>

Results:

a:2:{s:5:"stash";N;s:7:"bundles";N;}

So a is the number of variables into a bundle, S: the number of characters of each variables. What is N ? I do not understand this output format, it seems as JSON. What can I do with this output:

a:2:{s:5:"stash";N;s:7:"bundles";N;} ?

How to use it, and only extract stash, bundles data, coming from {segment_x} ?

In my opinion, you are confusing bundles with lists. Stash lists will provide the functionality you're looking for (which is basically to group variables into an array). Bundles are merely used as a way of tagging variables and/or lists so they can be cache-busted independently.

Follow the examples in the documentation for set_list: https://github.com/croxton/Stash/wiki/%7Bexp%3Astash%3Aset_list%7D

... and get_list: https://github.com/croxton/Stash/wiki/%7Bexp%3Astash%3Aget_list%7D
