How to show values of extended fields in Profile?

I am using the Profile snippet in the Login addon.

Users can register with a form that has some select boxes that allow multiple values. Among other things, they can choose which languages they speak. For this I have a select box with six languages. The values the user select end up in the database as an extended field which looks like this:

"languages":["French","Spanish"]

So far, so good. My question is: how can I render these values in Profile?

I have tried [[!+languages]] and [[+languages]] but this gives me no output at all. After reading this http://rtfm.modx.com/display/ADDON/Login.Using+Custom+Fields I even tried to do [[+languages.0]], just to see if I would get any output. I didn’t.

Is what I am trying to do even possible with the Profile snippet?

I eventually figured something out but I don’t like it much.

Complex field values (i.e. field values which are kind of like arrays) are accessed like this: [[+complexfield0]], [[+complexfield1]] etc. And NOT, as the docs suggest like this: [[+complexfield.0]], [[+complexfield.1]].

So, to summarize: if you have something in your registration form like this:
```
<select value="" size="5" multiple="multiple" id="languages" name="languages[]">
  <option value="French">French</option>
  <option value="English">English</option>
  <option value="Spanish">Spanish</option>
  <option value="Dutch">Dutch</option>
  <option value="Chinees (Cantonese)">Chinees (Cantonese)</option>
  <option value="Chinees (Mandarin)">Chinees (Mandarin)</option>
</select>
```
And the user selects French and English, you will have the render this in the user’s profile page like this:
```
[[+languages0]], [[+languages1]]
```
Of course, this means that you’ll first have to figure out how many values the user selected. This all seems very cumbersome to me. Isn’t there a better way?
