Let’s say that in this DSL,

two

is a child of

one

, and

three

is a child of

two

Copy code

one {
  two {
    three {
      two { … } // problem
    }
  }
}

Here, the programmer thinks that the second call to

two

is being called on the receiver for

three

, but it’s actually being called on the receiver for the outer

one

- yielding unexpected and likely difficult-to-debug results. Does that make sense?
