&gt; I don't understand the side-effects issues you mentioned.
when evaluating hierarchy you have to execute lambdas, so that you get nested “describe” calls, and since they are just lambdas, they could establish some shared state:
```
describe(“a") {
  val db = connect()
  describe(“b”) { … use db … } 
  describe(“c”) { … use db … }   
}
```
As soon as you execute describe(“a”), you get “db” captured in lambdas for b &amp; c, which keeps connection, etc
