Building a greenhouse universe

Once we've named a category, it becomes easier to notice when something belongs to it.

We don't have to decide in advance. We just recognize it when we see it.

universe Greenhouse {
  describe { ... }

  concept TomatoPlant {
    describe { ... }
  }

  concept WateringCan {
    describe { ... }
  }

  concept Plants {
    describe { ... }
  }

  concept BasilPlant {
    describe {
      A small basil plant with bright green leaves.
    }
  }
}
