From Mattwyne's fork. This is great. Thanks for taking the refactor further.

I think this would be a great example to share on the Cucumber Wiki.

Multiple similar steps
Refactor steps to the collector step
Refactor out the helper
I think that if we showed the first version with the redundancy within the step definitions, then my step at refactoring, then your final refactoring step (a beautiful bow),
