Like in "actions are blocks of text written in the target language"?
Then I understand why we have @headers or @members. Thank you very much.
(But.. mm.. why not @scope? :)

 To prepare such test data, I get into the meaniest, nastiest frame of
  mind that I can manage, and I write the cruelest code I can think of;
  then I turn around and I embed that in even nastier constructions
  that are almost obscene.                                  -- D.E.Knuth
