There was an implementation of it that didn't quite work for me in http://github.com/dchelimsky/rspec/commit/45a6837 
  so we reverted it. I have zero personal interest in this feature  
(use of which I find to be an anti-pattern) but am open to applying a  
patch as long as it meets criteria described in http://rspec.lighthouseapp.com/projects/5645/tickets/28 

Until such a patch comes my way, you can re-apply the existing patch  
(probably have to use git-format patch and tweak some things - any git- 
pros got advice on the best way to do that?) and it should work for  
most cases for you.
