should_assign_to extensions (:includes, :excludes)

Hi,

Would the attached patch be something you'd consider adding to shoulda? Having only just got started using shoulda I thought it might be useful. Wasn't sure exactly where I should be testing the extensions so apologies for the lame tests... the patch is more of "good/bad idea?" request than a "please consider for committing".

Cheers.

What's the use-case? It sounds like it'd be used for testing an index action, but I'd like to confirm.

Thanks!
