„This will render an erb file with a haml layout:

get('/') { erb :index, :layout_engine => :haml }

Whereas this will cause all markdown templates to be rendered with an erb layout.”

Although the index template is rendered with erubis, the {%= @title %} chunk
is not rendered with erubis. See the gist example.

I want to render the index template with markdown and with erubis:

erubis(markdown(:index))

and expect the following output:

<p>Hello Markdown!</p>

Are there any chances to make this work?

I use this trick in my blogs to set titles and to generate
links to static assets (images, css, javascript).
My blogs are powered by the Sinatra version <1.0 and
my sinatra-rdiscount & sinatra-static-assets extensions.
