[rbehave-users] Defining blocks only once

[dan at tastapod.com]

Hi Jake.

Each step (given, event or outcome) is stored in a separate hash, so it
doesn't matter if their names collide. However I quite like the idea that
an event in one scenario can become a given in another, so I'm open to the
idea that we could store them all in one place.

On the other hand, have you seen GivenScenario? This allows you to use an
entire scenario as a given to another scenario. You identify it by name:

Scenario "something happens" do
  ...
end

Scenario "something else happens" do
  GivenScenario "something happens"
  ...
end

There's an example in the game-of-life sample code. Let me know if this
helps, because I would prefer not to put all the different event types in
the same bucket.

Cheers,
Dan
