Does not play well with Rails < 3.2

Since there is a dependency on activesupport ~> 3.2

I've toned down to > 3 (which rules out Rails 2.x.x support)

Would it be enough? Or would < 4 be better? That would include Rails-2 and 1 (Read: activesupport 2 and 1) support.

I only use it for #symbolize_keys and #delegate - would it work? How to test?
