HAML Filters in the Helper

Helper functions can receive the block that they yielddisplay in the block. Sometimes I would like this block to be specified with a filter. For example:

= doc_page title: 'FAQ' do
  :markdown
    # Welcome to the *FAQ*

This is not so dry as we always write doc_page and markdown together. Can I get a helper method to accept a block and pass it through a HAML filter. Sort of:

= doc_page title: 'FAQ' do
  # Welcome to the *FAQ*

In this fantasy doc_page, this is a helper method that performs some settings and then transfers the content using markdowns, which allows us to declare :markdowneverywhere and make the world a DRYer place.
