Notice that in the ERB examples for link_to_unless don't actually include
any raw HTML text within the block; that is, the entire block is within the
<%= ... %>. You need to do the same with Haml if you want to use the helper.
That means that you can't use = or any of the HTML-generating Haml code; you
have to use
- "<strong class='current'>#{h name}</strong>"
instead.
