Do you know a custom tag to increment a value in a Django template?

One very annoying thing with strict MVC is that you can make the smallest processing in template. While it's usually a good practice, in this case it gets in the way: I make a for loop on a queryset of a lot of objects and display some attributes; Attributes are properties, making heavy processing (I don't want to trigger them twice). ...
