I was looking through the documentation of the overall mustache spec vs any
implementation:

http://mustache.github.com/mustache.5.html

I don't see any other way than going the route of defining a lambda and
adding it to the model instances as you passed them in to render.

It does look like the Ruby implementation has the concept of helpers, and
checking the pystache code it looks like it has some ability to create
Modifiers? Is this what you're referring to?
