rspec users - Mar 2013 - Passing variables to custom formatters

Guys,

I observing old mail

http://rubyforge.org/pipermail/rspec-users/2010-March/016638.html

and from it I understood that options hash is more side effect then
proper way for passing variable from spec to formatter.

So is there any official and supported way for doing that ?


Thanks a lot in advance,

Yury
