Signal that next step is of different type

Consider:

  Given something
  And something else
  Then it happened

  or..

  Given something
  Then it happened

  and..

  @When("something")
  public void something() {
  }
  @When("something else")
  public void somethingElse() {
  }
  @Then("it happened")
  public void itHappened() {
  }

I'd like to be able to know in something() whether the next step is of a different type or not.

  @When("something")
  public void something(@Named("lastOfStepType") boolean lastOfStepType) {
  }

This is particularly useful for UI interactions (WebDriver etc).

Given I am have a hat in the cart
When I purchase with credit card
And I specify an alternate delivery address
Then I should see a warning about different addresses

I might want...

When I purchase with credit card

... as a standalone, or with refining AND clauses. In the last of the when lines that's pertinent I may execute the whole set. When in this context feels like a continuation of sorts.
