We step back

Building a greenhouse universe

At this point, we've seen a few specific things.

Two plants. One tool.

It's often helpful to step back and notice what they have in common.

universe Greenhouse {
  describe { ... }

  concept Plants {

  concept TomatoPlant {
    describe { ... }
  }

  concept BasilPlant {
    describe { ... }

  concept WateringCan {
    describe { ... }
  }
}

This doesn't change the plants themselves.

It just gives us a way to talk about them together.
