The way Rails helpers work is that they're defined for the ActionView::Base class. This class is then instantiated, and it's used as the context in which the template is evaluated. To specify such a context for Haml, you need to pass the ActionView::Base object to Haml::Engine#render. Note that if you're doing this from within a helper, "self" is the current ActionView::Base instance.
