----------------------------------------------------------------

I agree that freemarker is not a programming language. However, there are at least 2 scenarios where using it so to some extent helps a lot:

1) When you can't change the backend data - they are given and you are there to make the most of them.
2) When preparing the data in the background would actually take more computing than aggregating them in the template.

For that, a flexible maps would help a lot.
Thanks for the API workaround.

> It would be nice to assign to a map this way:
> {code}
> <#assign map["key"] = 1>
> {code}
> and also 
> {code}
> <#assign map["key"]++>
> {code}
> So far I think it's like this but can't get it work:
> {code}
> <#assign map += {classification.classification : map[classification.classification]!++}>
> {code}
> Thanks for considering.
